Re: painting back of seats (mjfox)
I repainted the backs of the seats on my 92 with beige interior last year. Get some vinyl dye in the correct color in a spray can. Mid-America, Corvette America and ZIP sould have cans at a reasonable price. I got mine from Corvette America and the color was an exact match.
You need to remove the backs from the car to prep them. The back cushions are held in place with 4 clips. About 6 inches from the bottom of the seat back, push in at the edge to release the rod from the clip. Do the same about 5" down from the top. Once these are released, just pull the seat back from the clips on the other side.
Remove the cable end from the seat back release and remove the trim piece. The seat back is screwed to the seat frame hinge at the bottom, 2 screws per side. You should then be able to remove the shell from the car.
Clean the plastic shell with lots of soap and water (I used Dawn) and use Prep-Sol (available at auto paint supply stores) to remove any grease or oily film. I used a scotch-brite pad to roughen up the surface a bit so the vinyl dye would adhere better.
I shot 2 thin coats on the seat backs and let each one get tacky before the next coat. After the 2nd coat I applied a heavier coat and let it dry overnight.
Reassemble in the reverse order.
