if its really etched deep, and really bad, and ALL the methods i mentioned doesn't work.

consider getting waterproof high grit (3k and above) fine sandpaper, and wd40 (or equivalent lube) and do VERY LIGHT polishing.

please be reminded to take this step with extreme precaution, and try it out on small/corner unnoticeable areas first

ultimate compound (or M105) on the windows when the marks are really severe,

what say you?

personally it has worked for me.

1. Where to get those types of sandpaper?

2. Polishing by hand - means I apply a little WD40 to sandpaper and lightly polish the glass with it right?

Thanks for the help yeah.

1) hardware stores like ace hardware (doubt general supermaket has, but you'll never know)

2) apply on both sandpaper and a bit on the glass too (be careful not to get on to other parts other than the glass. to be safe consider masking the other areas, or use the "pen type" wd40, less messy )

Will post back with results when I get my hands on the sandpaper.

u can always opt for chemicals that break down the watermarks, I've personally used Waxco's Watermark remover in a small black bottle with yellow wordings. got it for < 20 ringgit .

Works like a charm! Just do NOT let it SIT to dry on plastic/painted surfaces as it is acidic and will eat through it given time.

It looks like water and has no smell, applied it with a soft sponge and gloves, rub until you can see the difference ( since it's liquid, it will stop forming water droplets and instead start sheeting ) .

But also note that if your glass has been treated with any coatings, this will most likely remove that coating .

If water just 'stick' on the screen in 'sheet', you're on the righ track. On a squeeky clean glass (without anything including protection) water would just sheet on it with minimal beadings.

Those pics looks like mine when I first got my new car. Soft99 Glass Compound Z worked for me. Can find it at ACE. M105 (or Ultimate Compound) worked also but, by hand, it's not as effective as the GCZ with the pad that came with it.

just sharing some pics of my noobie or rather virgin car detailing experience

Exterior: Washed, clayed, polished, waxed, protectants on trims and headlights.



Products used. MG should pay me some advertising fee..



End result. Not sure if its my 1 month old Ultimate Wax, or 2 week old Ultimate Quik Wax or 1 week old Ultimate Quik Detailer In summary i would say this shit works !!

Meg should really pay you back some money.

Couple month back, I thought my results should be the same... Mana tau, tak jadi.

eh how come tak jadi? what product you use? this is only my first time using Meg's products. previously on turtle and kit for my old car.. personally quite happy with the results.. although its really hard work.. especially the polishing part. lucky no need to always do that.. my fav products so far are the UQW, UQD, UP and NXT glass cleaner.

next challenge for me is the engine bay cleaning!! i need to go buy the products first.. my home minister really not happy that i'm spending so much time with my metal mistress..

Ahhhh....nice work. Very familiar/typical beadings of UQD (I think la)....

and nice car too!
best looking in its class imo

Nothing to do with product, it is the method applied wrongly.

Beading jadi mcam bleeding.

haha yea, method is very important. as cincai do obviously yields crap results (any part of my car other than the front engine hood ROFL!)

but when done well, even cheapo rm20 kura kura wax can also look (and water bead) good!

where did u bought the new car kit?

bought from Meguiar's booth during the COTY2012 exhibition. Got 20% discount summore.. i think that was when it sold out. If you have any friends/family coming back from US, get the to buy it for you. So much cheaper. i got my friend to buy the Claykit from US, after conversion only RM69. Summore with 4 50g claybars. Over here is RM176 with only 2 50g claybars.

sell me 1 biji la!

Managed to find a hardware shop. Sadly, I was only able to get my hands on some 1200 grit wet sandpaper. The results, however, are pretty promising. Some pics.



Comments?

not bad! one thing though, no matter how "etched in" the watermarks are, sanding is guaranteed to remove it as it is abrasive (hence you need to be extra cautious)

as you sand, you will definitely sand off a thin layer of glass, and when that happens, the watermarks are pretty much gone

don't forget to apply lube (eg: wd40) to minimize the damage

I used clean water when doing the window sills. At first I found it to scratch the glass a little but I realized it was every time my fingernail hits the sandpaper

Going to resume sanding works next morning. Too many mosquitoes working their way towards my blood.
