Sorry I don't have pics but a customer come in yesterday with the worst water spots I've seen in my life. She wanted me to remove them. They're worse on the windows I tried chemical removal first didn't do a thing.. then I tried 205 and a white pad not a thing.
Then yellow pad with UC nothing. Then mf correction compound on mf pad nothing
Then mf compound with mf pad..
Nothing at all even touched them. You can feel the water spots (feels like sand paper). I tried steel wool also no luck.

I'm thinking sand paper? Any ideas how to remove this?

Hmmm - if the water spots are abraised then you should be able to take a razor blade to the glass, same that I do if there is overspray on a window. That may get it done to the point where you can chemical remove the spots..... which I suggest a very aggressive compound like 3M superduty on an aggressive pad done by hand first IMO. If it is that bad on the glass, the paint may be a lost cause. I was able to correct a vehicle last year about 80 to 90 percent but could not safely remove all the waterspots from the paint. If left for years the waterspots can get through the clear very deep! Good luck and hope this helps.
 
Yes these spots cover the car 100% I mean imagine the worst water spots u can possibly think of and then multiply that by at least ten and u might be close

GLass: Try 0000 steel wool and chrome polish, (yes, chrome polish) OR 3m Super Duty Compound. I get mine from auto body paint stores. Try in a small spot and see what happens.

Paint: Are you comfortable wet sanding? Did she sign a liability waiver? Have you told her you do not guarantee results? **ALSO inform her that water spots can COME BACK, depending on how deeply etched they are.

I always under-promise and try to over-deliver. Let's them know I'm being upfront and honest, and also makes me look even better once I get desired results. Keep us informed and good luck.

I used a product called Duragloss Nu Glass on some really bad water spots and it took them out of the glass. Be sure to clay the glass first though. It's only around 8 bucks.
 
Thanks for the help guys.. I wish I had a pic.. I would bet a weeks wages you've never seen spotting this bad though..

Can u wet sand windows

Do you have a rotary and some compound?

Generally speaking paint correction products aren't strong enough to cut glass but they will abrade surface contaminants. Meguiar's Ultimate Compound on an orange foam pad at 1200rpm should gain some ground on these.

Griot's offers some glass cutting pads that work really well and are right at home on both rotary and dual action polisher. Lake Country also offers glass polishing pads although I haven't used them yet.

Do a 12" X 12" section and gauge your progress.

CarPro CeriGlass is yet another option for you to think about.
 
also to consider. Car-Pro has a new pad for glass. That and some glass polish might be worth a shot. As others have mentioned, chrome polish works as well.
 
I don't have a pic sorry.. I'm hoping she'll come back then I'll take some.. but yes I have a da and a rotary I tried both with many products and pad combos my last effort was a yellow cutting pad I tried 3 or 4 different very aggressive compounds. First UC no go.. the megs mf correction compound no go.. then some REALLY REALL aggressive compound a friend gave me called car pro workout 1500 only then did I even BEGIN to notice a difference. But it was still worse than u can imagine.
I tries chemical removal.. I have some chemical stuff (forget the name) didn't work, tried vinager no go, steel wool with different chemicals nothing..

The only thing that even made the slightest difference was the work out 1500 on high speed working a very small section, working it in for a long time. I followed that up with megs UC and an orange pad, then megs m205 on a white pad.. only then could u even notice a small difference.
AND I MEAN A SMALL DIFFERENCE.

Seriously guys these spots are nit just spots they've streaked to.. and they are so thick I got inside and looked outta the window and it impaired my ability to see clearly through the glass tremendously!

Honestly I can't see how she can safely drive with it like that. She's lucky the car is painted white, if not it would still be white just not by choice. From the "spots" "streaks" "residue" or whatever you wanna call these monsters.

Have you tried spot washing with lacquer thinner, acetone, or anther strong solvent? This is more than water spots....

Yes I had some lacquer thinner that was my second go to chemical when I noticed the spot remover not working..
Your right this is much more than water spots.. I've never seen anything like it and I've been looking online at pics trying to find one that's almost like these.

I would use the following products from CarPro: rayon glass polishing pads and Ceriglass.

You can wet-sand glass, however, it will need correction afterwards (severe) and anything you use to correct it would have removed the water spots to begin with. IMO its a bad idea to wet-sand glass or go at it with steel wool.

CeriGlass and their rayon pads are excellent at correcting glass (removing scratches - not pits). So good, you can do it with a Griots DA. However, its very messy and takes a lot of work just to do a windshield (correction). You will not know how long it takes to remove the spots until you try, so if your going get involved in this endeavor, hope for the best - but plan for the worst.
 
Y'all google and see if u can find pics of the worst water spots u can find and post them and I'll see if it cones close. I been looking but don't see any.
