has anyone had experience wit painting/dying vinyl seats or door pannels? i understand some of the new primers offer the elasticity necessary but am afraid to do items like seats in fear it will crack off. i am contemplating a color change in my 76 300d while i am restoring it. the carpet and headliner are shot but the seats and door pannels are in serviceable condition. cost is a consideration. i now have green exterior and interior and would like to go with brown on the interior
