I did it on my ex's Mazda3 back when were dating. I think it cost me under $20 to do all four doors, plus the Super77.
Mark over-prices his items by an exorbitant amount.
The hardest part, in these cars, is getting the insert out and back on. Once you do that, the actual covering part is cake--(No, Beggz. Control yourself.)
Not on a Fbody, but it's the same process, after you've removed the stock insert. If you've ever laid down window tint, you won't have any issues doing this. I'm working off memory from a couple years back here, but basically:
- Go to a Fabric store. There are so many options for you to chose from. You won't need more than 3 yards, I believe. But take the dimensions before you go to the store anyway.
- Lay down the fabric over the insert. (I used micro-suede when I did this, 6 years ago). Then flip both over, so you're looking at the back of the inset.
- Cut around the perimeter of the insert, leaving at least a 2" flap of fabric that you can fold back onto the back of the fabric.
- Spray an abundance amount of Super77 on the face of the stock insert.
- Center the fabric over the insert appropriately, then set it down slowly. Make sure there aren't any wrinkles, and smooth it out as you lay it down.
- Let it cure.
- Then fold the extra fabric over to the back. Make it stay down however you want--Super77, hot glue, rubber cement, JB WELD!, industrial staples
- Attach the insert back to the panel.
- Cut a small X slit into the holes where the door handle bezel and whatnot go. Pop those in. DO NOT CUT OUT A "circle" shape. Only a X.
- Use a credit-card or something along those lines to poke any excess fabric into the crevices to make the insert look clean.
- Make sure you run your hand over the surface of the insert multiple times to make sure the fabric is making contact with the glue and staying there.
No In-Progress pics, but these are the finished pics from back in 08. We broke up a few years later, but they were still holding up for the next 3 years or so--probably still are, but I haven't asked--so you should be good.
