They key to painting the plastics is to make sure you do everything humanly possible to clean the heck out of it and get all grease and any crumbly parts off it. One thing I did a long time ago on my fist Jimmy was use simple green and water, then dry it, then I used some TSP and rinsed and dried it. After that I sended it all over because some of the areas were slick and had a litte of that sun rot on them that makes them really dry and grainy with pieces flaking off. Once I got the surface cleaned I did a good wash down with soap and water and then used IPA to wipe and prep the surface once more. Once I did that I used an adhesion promoter, then shot it with flat black Krylon and I let it sit in the sunlight and bake all day. Once that was setup I went back over it with matte clear a few coats, letting it bake and setup each time. It held up well over time but that was a long time ago so can't say how long it held up over the long haul but it was still in good shape the 4 years until I sold it.
