Is there such a thing as Madrid grain (thin) vinyl repair tape? I have some door panels that need repairs that are not offered in reproduction. What would suffice is some matching grain vinyl, but not the kind with the heavy fabric backing. It has to be thin and flexible (with heat). Black is needed but I plan to re dye the whole panel anyway.
BTW this is for a non Olds but still GM car.

Sort of difficult to envision what you want to repair. I wouldn't use tape to repair interior vinyl. I have used a vinyl/leather repair kit on the leather interior of a truck I owned. It worked well to repair a rip.

You can also get OE style vinyl or fabric from SMS if you're doing a concours restoration.

There are some very talented people that repair vinyl auto interiors that service used car lots nationwide. Get in touch with some local franchised car dealers and ask who does their interior repairs.

10-4 will do. This other car is a 70 Camaro with deluxe interior and thus deluxe door panels. Not reproduced and even Just Dashes can't hardly do anything with them. They can strip and reskin them but all the faux stitching is lost. So the better route is small repairs to cracks in the vinyl uppers
