The '56 DeSoto we restored has terrible scratches
in the back glass; Eastwood's light polishing kit couldn't touch them, so
we bought the more aggressive kit, and it was worthless too, on the back
glass. The owner of the DeSoto found this same site, Wayne, so I called
them and explained my plight. They were familiar with Eastwood's products
(told me that Eastwood's aggressive kit is basically a repackaged 3M
product....) Janvil's tech rep told me that if the Eastwood product
couldn't get my scratches out, then their product probably wouldn't,
either.
From reading the Janvil website, it certainly rang
true that the surface of the tempered back glass is very hard. The tech
rep actually complimented the quality of the DeSoto glass based on my
description of the Eastwood products (lack) of performance.
Side glass and front glass is not as hard on the
surface, and is more receptive to polishing. We have spent quite a bit of
time polishing with Eastwood's product on front glass, and I don't have any
worry about creating heat. The product needs to remain wet, and that in
and of itself helps keep heat down. We spin the buffer with a drill motor,
which is relatively slow.
The whole process though, is terribly time
consuming, and somewhat frustrating in its results.

Subject: [FWDLK] polishing glass
scratches
I'm aware of the glass polishing kit from Eastwood for
windshield scratches and that Gary Goers basically offers the same
thing. Its cerium oxide and a buff whether you buy it here or
there.
But I found this on the internet advertised as the only
stuff that can be used by hand and wondered if anyone has tried
it.
Anyone?
Glass shops have told me on a vintage windshield they
would rather not machine polish because the heat can crack that old glass and
they don't want the liability. I figure since they are supposed to know
what they are doing, I'd probably stand a good chance of breaking a windshield
if I go after some well-aged wiper scratches.
Any feedback about this?
Wayne
