Gamers Arena.

Or online like Gwing, Toypanic, Crux.

Gamers Arena sometimes stock old kits reissues.

If not, you have to look from HLJ or Amiami Japan online stores or ebay.

My friend got a can of acrylic clear spray, reacts oddly to difference surfaces. When sprayed on bare plastic, it's a nice matte coat. If sprayed on painted parts, it's semi gloss.

I've got a few cans of Samurai Spray. When I do short bursts, I felt like it's spraying watery mist instead of just mist. Hope it makes sense. I felt like it lacks pressure. I might try your warm bucket method though as I have another full can sitting there.

Could you elaborate more on "flat gel" tried googling it gave me a lot of random results.

i never seen Samurai Brand in shops, so i don't know how it works. wattery might mean you aren't shaking it well, you need to do it like Cocktail at the bar. it also depends on the QC of the paint mix, sometimes the batch has too much solvent. and also, has to be done on hot & dry days. if it's too wet, you should further the distance before spray, and like i said, max 1-2 burst on each area per session. the warm bucket mostly helps when you are using it for a long stretch as more you use it the colder it gets thus lower the pressure output. how much are the samurai mattes btw?

flat base is what Mr.Hobby call them. Google Mr.Hobby Clear Flat Base. there is a rought version no idea what it means.

http://mfpilot.com/clear-flat-base-standar...or-acrylic.html

put some in the clear + thinner mixture and use a flat tip brush to stir.

also on the different reaction, bare plastic is very smooth, thus you get a very glossy look with the spray, on painted parts, the surface is probably not smooth with spray textures, thus when you spray clear gloss on it it will look less glossy. to make it look glossy you need wetter coat so the coat fills up the gap between the spray dots.

to do so you have to use burst spray and move the can from 1 side to another at a distance very quickly each spray, after 5-6 bursts you should get a smooth & clear wet finish.

Firstly, you've always been a great help. Thank you very much.

The samurai costs around RM10-12 per can (each 400 ML).

I'm unsure, I've shook the can like mad already. It could be some conditions that were not met. I could be spraying too far/near or it's just not warm enough or like you said, too much solvent. My friend used the same spray can but he got a nice matte finish coating. I've got blotchy patchy finish like below.
[attachmentid=9123576]

If the warm bucket method doesn't work, I might try to decan the samurai and use AB. If AB doesn't work as well, then I'll just fking buy bottled paints liow
*
why decan a rm10 canned coat when you can purchase a bottled coat for rm10?

when you say blotchy patch, means the coat is too thick, either you sprayed too close, or sprayed too much. like i said, a burst from far distance will give you dotted texture feel, so only do 2 burst each time. you just want the spray to touch the parts you are coating, not "Blast" it. for matte you have to shake really well of the gloss & matte mixture won't be even and you get a patch of gloss here and a blotchy patch there.

but does it help to reduce nub mark and white stress mark?

i haven't used it. both sides are sharp, but only 1 side moves when you grab it.

people saying it does cleaner cuts, which means smoother cuts closer to the surface. minor sanding might still be required but saves more time.

stress mark usually done when the cutter "pulls" the plastic when cutting due to not sharp enough. so i'm guessing it will reduce stress marks too. but it's good on parts cannot be sanded like special coating parts.

if someone has exp would be good if can tell us the do's and don'ts as i read you can damage the godhand.

the one sided blade design actually works that is why China has been copying the design as well. Unfortunately, the price of Godhand before is acceptable but right now, even without mark up, it is really expensive.

I have bought mine 4 years ago and the price has increase at least 50% today. The design works in a way that it cuts very clean and there is little to no stress marks. The single blade design motion is similar to you cutting a plastic with hobby knife. Stress marks happen when the plastic is pulled when two blade is crushing the plastic (more so if the blade has been used for some time).
*
what is the screw at the side do? limit the opening of the blade?

when you cut, you rest the non moving side on the nub and cut away?

the older version is 4000yen, now it's 4800yen, but still, under rm200 lo. long time ago i already hear people say it cost over rm200.

Some references for those whom is interested in diy:

1) inner condenser all cut and replaced with clear parts duplication and added with UV leds
2) outer condenser cover sprayed with clear red luminescent paints
3) head eyes replaced with clear duplication parts and added yellow led
4) shoulder and other belts replaced with laser stickers and clear cut out phone covers
5) details scribing and pla plates mod
6) 3rd parties 1/60 decals

it is possible to achieve it cheaper way, but sure is heck of a work to do... rclxub.gif  rclxub.gif

and now there is another interesting tech called fiber optics, sure will make it more interesting!

so where do you get clear part duplicates and aren't the LED vs Non-LED version same except no LED? at least for the latest PG.

do you use internal batteries or A/C plug or external battery? how do you work on the plugs? can't find one that is small enough to look good.

I used SMD (Surface mount led) and those clear parts i duplicate my self using epoxy. i connect external power and you might notice theres a wire there.. nod.gif  nod.gif  nod.gif .

usually smd doesnt require much voltage to work with, but for those small sizes smd sure is hard to solder and handle. so if you r looking at rgb smd for that cool color change effect that would be another level of led mod... (require programmable board such as arduinno)

what you used for the mold & cast? i think duplicating all the parts takes the most time. you should have just made few sets and sell it on ebay.

i bought those clear epoxy for those usually used in key chain souvenirs that you saw in beaches (clear cast keychains with tiny crabs inside),
longer curing time clearer results.

resin and epoxy duplication takes a lot of try and errors without proper tools... i might go crazy... rclxub.gif  rclxub.gif  rclxub.gif

now trying to duplicate tokugawa mk2 helmet also giving me hell of a time now...

you used epoxy to reproduce, what about the mold or you call it cast what material you used?

and where you get them? i know Central market sells them but expensive.

and since you already have the cast, why not make more and sell them?

btw did you do it in well ventilated area as they are suppose to be real toxic.

For large parts i used silicone mold, but for small parts like this 1/60 exia i just used Oyumaru Reusable Molding Stick.

making mold is as difficult as resin duplication, i have ended with a final silicone mold after 6 trials still the casting result requires lots of touch ups.

summore silicone mold making are all one off unlike reusable molding stick.

reusable molding stick also strictly for simple parts only... too complex the molding stick cant reach to the details.

how much time & money those clear parts cost?

below rm50 can cover a few cast and mold process, enough for you to do 3-4 duplication if everything runs smooth.

as for time the curing for clear epoxy takes a day, resin faster within minutes (hence chance to fail at success cast also fast as you rushing)

that also depends mix ratio correctness (if you hands on you will see why you need a weight balance for it, after a few casting to container already need to change. hell of a messy work to do)

resin casting are way more hazardous and strong smell and messy (my spare room already become workshop) thats why its a so demeaning work to do...

also silicone molding process is messy and sticky and hard to clean (normal detergent and thinner wont work in this case)
*
the mould (the one to make the parts), you just take out the material and press on the part you are replicating and leave it to dry, or still need mixture?

Am talking about Bandai Decals, i guess it's a little thicker, after dry for days they do stick nicely, but when i dry them with cotton and leave it for few minutes while working on the decals and i proceed to do other parts, perhaps by accident i would touch the decals, and they either drop or stick to my thumb then went missing, yet i see some people do decals in one go and have no such problem sad.gif , now have to find identical decals to replace the missing one
*
how long you dip the decals in water? if too long, the decal loses it's adhesiveness.

when you use setter, if the decal is too wet the water will wash away the setter, or when you adjust too much the setter becomes ineffective.

and when you use the softener, you cannot apply on the whole decal 1 shot, have to start from 1 edge dry up then the other, and finally apply sparingly on the middle. use too much or 1 shot you risk decal coming off.

regarding doing multiple decal, if the decal is too close to each other that the water may sip into decals applied, better spray a top coat to seal off the applied decals 1st. if not have to make sure the water doesn't touch applied decals.

usually we apply decal part by part before fully assembly, when you work on 1 side just make sure you don't scratch the other. you don't need airbrush for top coat just to seal the decals, any cheap DIY clear coat will do the job. just 1-2 burst will seal the decal and dry quite fast. once you finish the decal you can spray thicker clear coat to even out the edges.

well, i don't build Gundams so this is what i read from internet. all the best.

if water slides are giving you problem, can always use the traditional stickers.

Thanks for the tips, I enjoy water decals more than anything, but sometime hesitation to get things done cause me trouble, usually I will do one side, let it dry for hours and do the other side, guess I should just stick to the principle to avoid the mentioned problem, now doing it at slower pace like what I did with psycho Zaku, took two weeks to apply all decals
*
water decals dry almost within 5 minutes after using cotton. the longer you wait, the less sticky the decals are because when they are still slightly wet the mist helps them stick.

after you done 1 side just top coat it. if not the other side bound to get rubbed.

from my experiences, water decals doesnt go well if your kit is unpainted, especially straight oob and assembled the kit without washing it add the risk of decals doesnt stick. oob runners tends to have slight residue of oil (although i find bandai kits were the least) and smooth plastic surface also another reason water decals doesnt stick.

now all my kits were painted before decals process but i got that issue when i commission my clients kit with portion that skip paintings.

my rule of thumb is:

1)dip water decals with time just enough the decals able to slide out, bandai (when i try gouf custom decals) tends to take longer to separate.

2)when slide to the target area, cotton bud press slightly on the middle of decal (to ensure decals hold in place), then roll press from side to apply even pressure in order to remove excess water underneath.

3)Finally slightly apply mark softer just enough solution to cover the decal and wait a few seconds, repeat the cotton bud press and roll process.

this way has worked like a charm for all my kits even without coating, even after leaving it months or years, decals still hold. (reason i dont coat it is chrome painted kits tends to loose its shine after clear coat...)

you did not use mark setter?

the mark softener should be used from 1 edge to the others then on mid to avoid floating the decal.

I usually cut one or two at max then dip in w ater then gently test it with cotton to see if it move, once it move I will apply it to the kits, could the problem been I gloss coat one layer before doing decals?
*
gloss coat suppose to make the surface smooth to maximize contact areas between decals & surface to ensure decals look as flat as possible. it should actually increase grip due to the surface characteristic. your problem is either you soak too long in water or adjusted too much until the decals lost it's adhesive nature, mark setter should have corrected the issue and softener should have sealed the deal, or maybe you applied too much softener at once until you flated the decal without realizing.

anyway just top coat the part once you think you done enough progress.

i only had 1 decal fall off because i adjusted too much it was Bandai decal (setter + softerner made it stick), but then again i never built a ver. Ka so i don't have so much decals to work on, and i usually skip alot of small warning decals because from far those decals look like dirt.

like i said, just use a cheap gloss can and spray 1 burst on the surface to seal it. you can use more top coat when you finish all the decals and then follow up with a final top coat.
