Re: Brakes squeak on rims after painting.
I'd remove the paint from the braking surface.....if you get stuck in a rain storm...you will have almost no braking whatsoever. Also, after you remove the paint- run some sandpaper of the braking surface and your brake pads as well- they probably have a build up of paint.
How do I know this?
I did the same thing a few years ago with one of my beater bikes and ran it into a drainage culvert at 20 mph in a rain storm because I painted the rims:-)
If some's good...more is better and too much ain't enough.
