I've painted over a couple chrome handlebars. I roughed them up with a flap disc on my angle grinder before spraying. I think I've only used a flat paint. Not a show finish but good enough for me. Just touch up if gets scratched.
Yeah. Sand with 40 grit then switch to 80 after its all roughed. Then I use dp90(ppgs epoxy primer.) No idea what DuPont, Sikkens, Matrix, or any other brands names are though. All the shops I worked at were PPG only. Well, except Miracle decades ago, and you don't want to use anything they were.
I scuff with 60 grit then use etching primer before paint.
With handlebars or one piece cranks you have to be careful installing them,if you scratch them just do a little touch up.
Yeah, what they said, but don't skip the etching primer. IT makes a ton of difference.
FWIW, a lot of higher-end road bikes from the 70s and early-80s came paint-over-chrome, straight from the factory, and the finish always looked great on those, so it's very possible to get a pro finish, if you do this right.
Same here but my buddy paints and strips air planes you should see the paint on a 25 year old airplane it falls off it's krazy how it comes off I'm going to see what happens.
