I've thought about doing this as well, but don't know where to find vinyl that'd match. The one option I've considered is to use salvage yard mb-tex from door cards, seats, b pillars, etc. But finding that in 1) the right color, and 2) in decent enough shape, is difficult. I wonder if a call to GAAH would yield results; if so it'd be more expensive for sure.
I swear by Duplicolor Vinyl and Fabric spray, the Desert Sand 98% matches my light tan interior :thumbsup::thumbsup:
