I cleaned with alcohol after barely scuffing with 600 grit paper - its new plastic so, not much prep.
Light coats to start, and applied about 5 coats of paint with a touch up gun - there are lots of angles.
Followed recommendations from Eastwood company, and like our bikes, this is a single stage paint. Fast flash time of about 5 minutes between coats, no clear coat (though maybe someday, if I do the whole bike!
