i also hear SEM is good stuff. i have a can, but haven't had the time to paint the interior yet.
also a good preventative thing to do is to dress some PrimaNero while your car is new onto
the panels. it reduces the plastic from catching to reduce scuffs. i use it 50/50
dilluted in water. amazon has it, most detailing shops have it.
i have zero scuffs on the door panels, etc on all my cars even though they get kicked
often.
but the dumbarse smog check goof scratched up my a-pillar a while back.
i didnt dress any on the a-pillar.
gotta always look out for stupid.
