Laminated verses Toughened Windscreen

[Jose]

David, there are businesses that polish the windshields to like new condition.

I've seen this done in those car-restoration tv shows, they do a very good job of restoring 1950's windshields.

Glyn,
Can you say a few words about "diamong media polishing"?
How it works? who does it? etc.
P1B79909DN has its original windscreen (Sundym) and, over the years, having been driven throug dust, hail, and sand storms, the glass is slightly pitted/scratched. I don't want to replace it, but if it could be made clerer again, that would be wonderful.
Thanks
David

Hi David,
I was talking about polishing flat glass. Done using varying "grit" Cerium Oxide or Diamond powder in a water slurry on machines that look like this. Slow speed, semi flooded grinding or polishing to keep temp below 70 deg C I understand.

This can be done manually (with power tools) on curved surfaces with experience to prevent distortion.

There are some warnings that polishing scratches/pits out of windscreens can weaken the glass. I can't vouch for their veracity.

I have no idea who can do this in the US. When I lived there this was not something I explored.
