There was a thread on here a couple days ago about this stuff. I figured it would be perfect for my faded gray door panel inserts on my 95 EX, so I headed to the local autoparts store and found it in the paint aisle.
I went ahead and pulled my door panels (kind of a pain, since the Chilton's manual I have is VERY vague (so vague it doesn't even have instructions for my year/model)). Anyway, got them all apart, and I was disappointed to find that I couldn't remove the inserts to paint them seperately from the vinyl panel. They're held in with "plastic rivets" (at least, that's what it looks like). So, I got to work masking off the vinyl. The only thing I could get to stick was electrical tape. Masking tape wouldn't stick at all to the vinyl (probably cause it's got armor-all on it).
After I got everything taped off, I went ahead and sprayed the stuff on... It goes on pretty much just like spraypaint. The one thing I wasn't satisifed with was the fact that the one spot there was still discolored a bit. However, this is probably because the fabric is all crushed down and stuff, since that's right where I rest my arm when I'm driving.
After the stuff dried completely, I pulled the masking off and re-installed all the components into the door panels and put them back on the car. I was surprised, the inside of the car doesn't smell like aerosol at all.
I was pretty skeptical at first, but this stuff does seem to work. The next thing I will probably do is my front seats, since they're the same faded gray. The paint does leave the fabric kind of stiff and bristly feeling, but I rubbed it with a stiff shoe-cleaning type brush to soften it up a little bit, and when I did this, the paint didn't flake off or anything, so it seems pretty durable.
Anyway, here's some pics, for those of you who are visual... Sorry for the crappy quality on a few, my camera just isn't that great...
The test subject... That's my brother's Impala in the BG
The product. As you can see, I also picked up something for the exterior as well, but that will happen tomorrow.
