none of the paint came off, but then again, i did not install them myself. a buddy of mine that works as a bmw/ducati dealership put them on. he said the front rim got scratched a bit, but i cannot find it. i guess it is under the tire. as for paint flexing, not sure. i would suppose that it doesn't, but i have to taken the bike out yet. when i do for a while, i'll let you know whether it chips/breaks or not. to answer your question about the paint, i prepped the wheels, hit them with 3 coats of self-etching primer (duplicolor), then 3 coats of gloss black engine enamel (duplicolor) and then 3 coats of clear (duplicolor engine enamel).
since i am posting already, here are some more pics of progress:
put the front brake arm on the wheel:
the front wheel is on the bike. yeah......
and
also, it's been a week since i put the last coat of clear, so it means i can wet-sand it and get it ready for further work. i hit the tank and the seat with 1000 grit wet sandpaper. it took a while, but the results are great. smooth as a baby's butt. i put the tank and the seat on the bike to start figuring out the location of the stripe. well, here are the tank and seat on the bike. they don't look shiny because they still need to get a few more coats of clear.
later,
