After thoroughly sanding the surface, I've prepped flexible plastic bike parts with SEM 38354 Plastic Prep - a product I got from my local auto body paint supply store. I then prime the surface with a good quality rattle can flexible primer (I use SEM 42013 High Build Primer Surfacer). I recommend a flexible top coat as well to finish the job. In the end, I can't guarantee the paint won't crack or flake when scratched or bent, but using these type of products that are designed specifically for plastic, should increase your odds that it won't.
