Vinyl holds up well. It better than the average persons spray can job on interior parts. That stuff chips really easily. This vinyl is permanent in the sense it doesnt just start peeling or anything, but is easy to remove back to stock or if you want to change the color easily.
Domi's is still looking good and I have also done it in my RX8, and i love the look.
just be patient with it...especially if you plan on doing it like Domi's. None of the pieces we wrapped have enough space too tuck in the vinyl...so your trimming is going to have to be perfect lol
