I'm welding a roll cage in my eg and when I was grinding alot of sparks hit my windshield and left black spots that won't come off. They are not deep or anything and I was wondering if there is any way to polish them off?

 

i am dealing with the same thing. so far nothing has worked and will have to cough up 350 to get a new one installed

 

Go to an autoglass shop and ask if they will sell you some polishing power... it takes out blems in the surface and embedded metal scrapes or similar. It looks like a fine clay colored powder.

barely did anything for me takes out VERY SMALL nicks. mine are small to me you can barely see them but you can feel it. and didnt do jack for me.

 

there is a couple different grits.... I've used an orbital sander to aid in the work.... worked pretty well. In my case it was for getting out embedded aluminum scuffs from the edges of sanding blocks. It did take out some of the pitting from day to day driving too.

 

hehehe yeah that sucks ,ive done it but ,it was from my welder and on the outside ,i guess this is why they sell welding blankets

i dont think anything can fix it ,at least not mine haha

good luck bud

 

Damn, live and learn. I guess this is why I see everybody take out there windows when doing a major project like this (14 point cage). The method of do it all at once is totally the way to go, what I did is engine/paint/rollcage and it would have been nice to do it all at once on a rotissere.

 

350 for new glass is a rip off...I work at a glass shop and the glass is only like 70 bucks... then a top moulding is about 12 and the labour 2 hours or so.... it should be around 200 for a cash sale.

Oh and good luck getting grinding pits out, they actually deposit some of the metal you are grinding in the glass...and not only will they stay there they will rust over time.

 

3m makes a paper for this. We use it all the time and get cars from previous shops who didn't take this percaution.

yup, I paid $210 to have mine put in.

 

Spray some anti-spatter on the windshield next time--really helps.

 

i paid $140 for mine front windshield.

i'm working on a roll bar so guess i'll have to watch out for the windows in the back. GL

 

I did the same thing to my old window and nothing took it out. I ended up getting it fixed for free through my insurance company due a small crack that developed after hitting road debris.

 

when that happens it rapes windshield wipers.
its like sandpaper.


buy a new windshield!

 

i feel your pain we had the same problem, i hate to tell you though we had to buy a new windshield and yes it will not happen again!!
