Well after some deep deep digging with google and this site I managed to run across this old post http://www.whitearmor.net/forum/topic/27579-pvc-pasteis-it-possible/
Looks like I'll give this a try on some scrap and see how it looks. Only question I still have is, Do you think PVC will polish up the same as ABS with Novus? I'm doing research on this too, but no definitive answers just wondering what any RS PVC kit owners use.
