my duster with the fold down rear seat originally had a crinkle finish paint on the trunk side, when I remade it back in the 90's because I had foolishly cut holes in the original for speakers (hey I was 16) that's what I used. I had to re-remake it last year because it had to be sacraficed to get into the trunk because my trunk lock cylinder broke, I used spray on bed liner (herculiner, bought at menards) and am very, very pleased with the results in appearance and durability.
