idk... youd still have to do a lot of surface prep. any texture underneath is going to show through the vinyl. if i wanted flat black, id stick with wet sanding and a good etch primer.
id never personally vinyl my jeep. now my BMW on the other hand...
If you have a rock chip or some other deep imperfection it will show through, but vinyl will cover up a lot. As long as the surface that the vinyl is being applied to is stable (not peeling or anything) it will be fine.
Just go for it man... People know from experience that mods like RR steering are crap, but this is something new so its really just speculation on how it will turn out. If you are sitting around bored it will give you something to do. I really like the flat black but it would also give you the opportunity to do something crazy (zebra stripes) and be able to take it away when you are sick of it.
I have always wanted zebra stripes and now I think I know how im gonna do it!!
