I have a few questions about restoring quarter windows. what brand of high build primmer do i use? what kind of course and grit sand paper? I recently got my first fox body mustang 1991 lx about a month ago and can’t stand the way the quarter windows look. could you guys run me threw the steps of what exactly to do and any tips or tricks and do’s or don’ts? I as well planned on leaving the quarter windows on to save the hassle of taking them off. I want to make sure i do them right and don’t make any mistakes. Thanks

I redid my quarter glasses earlier last year when I did the body and paint work on my 88. I did consult with Davedacarpainter and a couple guys I work with in the bodyshop. To get the best results you would need to pull the glasses out. I don't see any other way to refurbish them with them in the car. Mine weren't too bad, they werent missing any material or anything. I started by taping off the glass part and blocking them out with 120 grid sandpaper on a flat sanding block to smooth them out. Here at the shop we have two part plastic repair kits that we use on bumper covers and such and that was what Dave and my painter here at the shop recommended I use. So after I blocked them smooth I used the plastic repair kit to build up and fill the low spots in the moldings and smooth them out again. Its a two part material, kind of similar to Bondo. You put it in a caulking gun made for the kit and it mixes it self out through a static mixing tip. You would want to lay that out with a spreader around the glass just like you would with Bondo. After its cured, you would want to block that smooth, (I used 180 I believe). Then, a couple coats of primer. Let that primer sit for 24 hours then sand that smooth with 500-600 grit sand paper, wet. I refinished mine with black basecoat and a semi gloss clear coat, then reinstalled the glasses, along with my interior trim panels. There is a character line that you are going to loose by doing this. I don't think there is any other way to keep that line in the molding by doing it this way and I was ok with that. Working in the collision industry made it easier for me because I had easy access to the materials and the know how. You could go to your local automotive paint supplier and get that two part repair material but it is pretty expensive, I think its about $60 for the kit, then you would have to get the caulking gun, not sure how much that is but its probably expensive too. If you choose to remove them, you will need a roll of Butyl tape to seal up the glasses to the body. They bolt in, and I think there is 9-10 bolts on each glass. There might be other ways to do it but that's how I did it. Heres some pics.

I have moved on from the shop I used to work at. It was nice when I was there because I didn't have to pay for any of the materials I used when I did my car last spring. It was good while it lasted. I couldn't do that at my new shop. I would get a discount on materials here at the new shop but it still would have cost me quite a bit of dough.

I think Dave used 3m8115 two part epoxy on his. I need to do mine too....but want to recreate the character line.


It's going to be very difficult to recreate that line. The original rubber is molded with that line in place. To try and recreate that line and have it be straight with a consistent depth and look correct... I mean, maybe if you are Michaelangelo with the Bondo you can do that, but it's going to be a 9 out of 10 on the difficulty scale, and only the most hardcore Fox Body fan will ever even notice that it's missing as it's fairly subtle anyway.
