Removing Windshield Swirls Scratches Wiper Marks on a 1969 GTO with Dr. Beasleys NSP GL by Mike Phillips

Great write up Mike. I pre-ordered this. I have been waiting for this since Chris Recana and I spoke about this months ago.

Amazing work.. I have a problem and need your advice.

I used Meguiar's Wheel Brightner (acid) diluted 4:1 on my driver side glass, sprayed directly waited about 20 seconds and wiped off. I was in a shaded area, but the glass must’ve been warm, it was a hot day. Apparently I etched the glass becuase I cannot get the streak marks out.

Tried high speed rotary w/ wool pad/heavy cut foam pad, compound/metal polish, steel wool, razor blade, more acid, alcohol, even a dedicated water spot remover gel, but nothing seems to get these streaks off.

I did notice the razor blade did knock them down a tiny bit.. but streaks are still very visible.

Since then I have applied a liquid wax so the sun won’t bake it in any further than it already is, and it has actually reduced the appearance of the streaks when looking at them straight on. (At an angle is when you can tell) I will attach pictures taken before applying wax

What’s your take on this?

Can NSP-GL be the product that’s going to remove these etched marks, or should I be looking for a glass replacement instead?

I look forward to your reply, Thanks!

Outstanding, Mike! I don't have the courage to work on glass like that.

Lets hope a lot of other people see this thread moving into the future and because of it - don't do the acid technique on glass. I've never been a fan of this approach when I know how to do both topical and sub-surface glass polishing.

Yes, I think the NSP GL will do the trick. The staining or etching you see is going to be mostly topical, but even if it is penetrated INTO the glass, the Dr. Beasley's NSP GL Glass Polish works both for topical glass polishing and sub-surface glass polishing.

Most important - at this point, you don't have anything to lose.

Here's the link to the products you'll need. You will also need some type of polisher. A rotary works best but any orbital that can maintain pad rotation will work.

You are correct. Acid should not be used on glass, although I’ve used it before with no issues (never sprayed directly though)

I have a dewalt rotary buffer, looking forward to trying NSP GL. Will post an update after. Thanks for your recommendation Mike.
