Just curious - not using any shampoo at all to wash the car?

Anyways, RM100 actually decent budget; assuming you're only requesting for product recommendations and that RM100 not being spent on additional items such as towels, applicators, sponges etc. Water beading effect, quite a lot of products out there within that RM100 budget - Soft99, Meguiar's, Osren, Mother's, Turtlewax. Do you prefer wax/paste/liquid/spray type application?

Try soft99 fusso coat, only about rm40 in shopee.

I havent tried myself but The reviews are great, best bang for buck and durability is very long.

You are right on one thing - washing techniques/cleaning methods will be the key factor in determining how badly swirled a car may end up. Anyways, thank goodness there are many products out there and tutorials designed to help normal plebs like us to become good at DIY detailing too.

I wouldn't conclude that paste/liquid/spray are better than another, although many old-timers swear by paste application in terms of their durability, but I can tell you, even paste/liquid wax [however light a coat is applied] may risk swirls on your surface if not done correctly [I know cos I myself learnt from experience  ]

Most importantly, you need to find a product that suits your needs best and ideally, leaves you the least work needed to get the results you want. Things like streaking, stains, watermarks, buffing trails etc - some products are very good based on reviews but when you use them, the end results doesn't look good.

Regarding your comment, do you do surface prep [claying etc] on your car's surface before applying wax?

Cool, thanks for sharing.

As for your findings, I would say meta cleaner is similar to polish. And most polishes can be called cleaner wax as well. Difference is just the name but it provides a similar result. Probably key difference is just the scent/pricing/abrasiveness?

Polish unlikely to cut through clear coat unless it was applied really haphazardly.

What product did your friend use on his ride, if you don't mind sharing?

Soft99 white vs black series is marketed where black is less abrasive (if any) than the whites, as black paints shows swirls easier
says to never use whites product on black cars
meta clean is for certain times use
not for everytime use

I have used Fireball tar remover to get the black water stains before, but chemically.. not confident to long term use it
most light stains can be removed with applications of wax, since the flow is on the rubber lining area

this says that the black stain is dissolved rubber
and can be dissolved chemically with oil types such as wax

My understanding is that Soft99 meta clean is a all-in-one product. Unlike some polishing / compound liquid which have abrasives inside, this product cleans 'chemically' as it contains solvents inside. It also leaves behind a thin layer of wax as well. I think no problem to use this to clean off stubborn stains.

I have one, used it once or twice and had no problems with it.

Edit : as for your friend's case, ask him did he follow the instructions on how to use this product? I might be mistaken but Sounds like he used a lot and did not buff off completely.

so it seems summore never heard of hahaha

got dodgy feeling but got wana try feel   due to an ok price

Lately rain water is very dirty. Even after I wax my car, after rain my car will be covered with black layer, can even write on it.
My shampoo is not able to deep clean the black stuff, seems like it will eat into the wax at certain places,
Anyone can recommend how to take care of this?
Change wax?

Car is white color
Using soft 99 fussy wax which gives a very good water beading

I usually just trial and error, see how thick the foam is

Usually 1:10 is good starting point and adjust from there.
If the product you mentioned is IGL Blizzard, try 1:20, I've seen videos on it giving ridiculous thick foam.

Try adjust the foam to be thicker? Or add more igl blizzard?
Im using the grit guard from admsolutions.

Im also living in condo, usually do rinseless wash with multiple mf cloths. Cant foam since it will flood other ppl's carpark..

1 pail with rinseless, mf dip n wipe until all dirty then change another mf. No need to redip but cons is u have to use alot of mf

I have grit guards but instead of using 2 bucket method, i just use 5 or more wash mitts, one mitt for each panel to be safe

5 at least.. but only if its light dust. Cons is my mf gets black quite quickly. Tried washing it with carpro but my mf still turns black

i dont really use the grit guards anymore, yes i avoid reusing the mitts in one wash.

i'm too lazy to fill 2 buckets and squeeze the mitts multiple times

What car wash shampoo do you guys use?

Looking for a cheaper option. Been using Koch Chemie GsF RM100, 50ml each time into foam cannon. Average RM5 per wash

Update 5 yrs RM70 diy coating still ok with regular maintenance and quarterly cleaning using clay cloth to prevent hard stains. Surface still smooth despite parked outside 24/7

Ok done water spot remover using rhino above with the final car. Truly saves a lot of time instead of polishing but noticed it kills of ceramic spray coated vs graphene spray coated. So a gentle reminder to reapply ceramic or graphene spray that you guys have once done.
