I have a piece of E-body door glass with some minor scratches that I plan to send off for polishing/resto. Does any one have any experience using these guys? I want to use my original and do not think I can get the results I need doing it myself.

It looks like Any other recommendations?

Thanks!

I haven't heard of that company but they sound promising.
I went through a lot of grief with that issue with my T/A restoration which still aren't resolved. The shop had someone in MI who I was told was an engineer who had developed a 2 part epoxy of some sort he would fill scratches, which was the method he used with in his polishing process. Otherwise you end up with low points and dips where scratches were polished out. This guy charged $50 an hour and the bill would end up however many hours it would take him, which on a Superbird in the shop at the time, the polishing bill was around $3000. Very expensive but the glass did look perfect!
He did this as a sideline and was backed up with a waiting list, so the shop sent my 1/4 glass to someplace in CA he'd heard about that had a similar process to try out, with he billed me 2 or 3 hours to removed the trim from the glass and pack it up to ship out there. Place in CA would never respond after he sent it, so he eventually said consider my glass gone, and we had no choice but to install repro glass on my car, which looks crappy and they never aligned it properly, and still isn't 100% despite several friends and I spending hours trying to get it aligned.
8 months later my quarter glass showed up back at the shop with the box marked "refused delivery", so at least I got it back, though not the 2-3 hours of labor I paid the shop to send it there.
Another shop helping me out recently said he has a glass polisher he really likes, so soon I plan to get my glass polished, and the crappy AMD(?)on the car now scrapped after the original glass get polished. I'll report back on how it works out.
Glass is another chapter in my restoration horror novel, and a sore subject with me you can see!

Thanks Brad - That does sound like a nightmare. I see from the website of the guy I found that John Balow of Muscle Car Restorations has used him. I sent an email to MCR to see if they would recommend them. No reply yet.

My glass is pretty good.and only has some minor scratches. The worst part is where it looks like a DA touched the glass lightly. You can feel it but not really catch a nail on it. I hope I don’t regret not leaving well enough alone.

Floyd..tried to send you a PM with a recommendation. Your box is full.

I bought a glass polishing kit on ebay and Im gonna try and do it myself....

Now that I think of it, there was someone here in this section I believe, who posted a thread about polishing his cuda glass with excellent results. That was a few years ago, so it would take some searching to find.

I remember that post thought it was for a challenger though it was pretty in depth with lots of detail.

Maybe this post ...

I don't know if this will help. When i did my Cuda the glass needed some TLC to bring back to life. As long as the scratches are just surface and not to deep you can do it yourself. There is a powder called erudite ( not sure if spelling is correct). you mix the powder with water and use a drill on low speed with a special adapter pad that comes with powder. The results are excellent if you the follow directions.

I used vinegar and steel wool on mine and they actually polished up good
