Hello Auto Geeks,

I wanted to petition the more experienced detailing corpus here to see if anyone has any advice for me... I have a client who has a lot of micro marring and scratches on his windshield from a sand storm a few years ago. He said it is difficult to find a replacement windshield with the right curvature so would like to look into the possibility of trying to get them out. Does anyone know of a product or method one could use to buff out micro scratches from glass like that? I've never attempted anything like that before myself.

Thank you in advance!

Thank you TMQ. Should have done that first for sure. Appreciate the response my friend.

I would not attempt scratch removal on glass on a clients car being a newbie.

Now on the other hand, if you have an agreement (in writing) that this is your first attempt at glass polishing and you may or may not be successful then go for it. Everyone has to start sometime.

BTW start on the passenger side first. Good luck.
 
Great advice. Thank you Rsurfer.

I have polished quite a few windshields and side glass panels and have no reservations about doing it. I use the CarPro Ceriglass product and glass pads on my rotary and it works phenominally well. There are 2 things I strongly suggest...1. keep working it wet. it's almost the same as wetsanding paint, and...2. cover EVERYTHING else on the car you don't want that sloppy, slurry mess splatter on to clean up later.

Here here on the cover up.

Like the work bench, the light fixtures,detail cart, your head etc.

Very messy job.
 
Do a test spot. I tried to buff out a scratch on a side window and really, all I did was start to haze up the glass around the scratch. I think it would have eventually removed the scratch, but then I would have had the haze to deal with, I decided to quit while I was ahead. My car has "soft" glass, it might work better on harder glass, but I'm done trying to polish glass.

Just order a new piece of glass.Anyone or almost everyone on this forum has not exceeded glass restoration without problems.Then if you screw it up he will be blaming you.Stay away and be honest with him.

How do you know you have soft versus hard glass?
 
Me too.

No good results and lots of effort for marginal results.

Cheaper and quicker to replace on front windsheild (only $200.00).

Actually looks worse after as ypu see all the RID's.
 
Use Lake Country glass pads, CarPro have terrible quality, they start to break apart when you remove them from the backing plate.

I have a BMW. On BMW forums, pitted windshields are a common problem and many members end up replacing windshields for this reason. They call it "seeing stars" and I had the same problem. So the common perception is that the glass is soft. But I don't know that anyone has done scientific hardness tests. Further complicating matters, my scratch was on a side window, nobody talks about those much, may be entirely different glass. I'm a chemist, pretty good at following directions, my clear coat is beautiful, but my attempt to polish glass using Ceriglass and Lake Country glass polishing pads and a Flex was a fail. I was just sharing with the OP that this is tougher than it looks.
