Have this job coming up tomorrow. Any suggestions on your recommended procedure. I have an arsenal of wire wheel acid, steel wool, m105, orange pads, and some old OTC glass polish and lots of poorboys and meguiars aio's. Any advice would be great. I have never delt with a car with such horrific water spots. The customer is only concerned with glass polish so it can be driven. The car has been sitting for years. All of the glass looks like this.

i'd start with apc wash
then try pb pws (white pad) and hope
also depends on if you have any chemical polishes (ie pb pro-polish or similar)

Good luck, keep us posted
 
I also thought about clr, but have heard acid is the best way to start then polish with something. Anyone tried acid on this before? Thanks for all of your advice. This place is great...

CLR is the "acid". Just a bit overkill for most automotive applications.
 
I would try CerriGlass with the CarPro rayon glass pads. It will abrade whatever is on the surface off, and polish the glass to clarity. If it can remove scratches, it can remove water spots.
 
I've also used #0000 steel wool on glass with some success. That said, I can honestly tell you that certain windshields are "softer" than others. I'm not proud of knowing that tidbit. ;)
 
I have seen a few cars with waterspots - it goes with this wonderful water here at the beach. On paint, I tried something called 3D Eraser - got a sample from a buddy and I got to say, stuff works. Glass is another deal -Eraser works but it may take 2-3 applications, I'd try the CLR, and see if any of the box stores like Lowes have anything. Next , try soaking a towel with 6% white vinagar in a shady spot and let the towel stay on the glass for 30-45 minutes. Someone mentioned buffing it, I'd let the chemicals do the hard lifting, I learned that the hard way on paint. If you look at most "waterspot" removers, they are all a version of an acid.
Good luck my friend!
 
I like waterspot removers but I would immediately go to a heavy-cut compound and a machine if it were me. With the right compound, I think you could make quick work of that.
 
wow, thought that was a morning dew on the window at first

good luck with that

dont even think my DP high performance glass restorer would touch that

i second the compound
or windshield replacement :)
 
I would try bon ami cleanser. I never used it, but was told it works. Please post about it when your done.
 
Get some pads and the DA and get to work. Ive had great success just using a yellow pad and some paint compound on windows before. They didn't look that bad but they were pretty damaged. GOOD LUCK! Lets see a 50/50 shot of that tomorrow.
 
Done. Took a few hours to get it right. Vinegar, and steel wool absolutely no help at all. So I proceeded to use a chemical glass polish(tri star spot check) by hand with bug scrubber and looked much better. Then proceeded to polish with da using orange pad and Poorboys polish. Turned out great.. Thanks for all the help. I had wire wheel acid but didn't try it. Maybe it would have sped the process up a bit but acid has always scared me after seeing what it can do to glass while working at a car dealership for many years. Seen many windshields replaced.
