If possible I wouldn't take all of the paint off of flexible plastic, getting good adhesion to it is difficult. Just surface sand and squirt.

You can go to a auto paint store and get adhesion promoter It works pretty good scuff sand use the stuff then paint

I might just try that. My previous rattle can projects didn't turn out so well. I sand the first part really good but then get lazy on the second piece. Adhesion promoter....more than just a primer coat? Something that etches the plastic?

Rattlecan primer

Wonder if that krylon plastic paint would make a good base primer? They advertise it as bonding to the plastic. I've seen the demo chair (white resin, which *nothing* normal sticks to) at local ace hardwares every once in a while. Might be worth talking to a local paint shop as well, and seeing what they recommend.

Yes a plastic paint would be better than normal paint, they are designed to flex more. But there are lots of plastics, some paints claim to stick to all of them and knida work on all, others are designed to work better one type. In my experience the factory paint is well matched, sticks very well, most others not so much. So if you have the factory paint, well adhered, I would use that as my primer, scuff it well and shoot your new color over it.

I think I might try the duplicolor system, they adhersion primer thing, and go with one of there semi gloss or flat blacks. They have trim paint but seems it's more for metal than plastic

I have used the dupli-color system and it works pretty well. There is an adhesion promoter for the first step and a product called bumper coating in various colors including a matte black. It adheres and flexes well, but doesn't hold up to scrapes with the local geology - of course niether does the plastic bumper.
