Okay, so I used Krylon Fusion, Paint made for plastics, I used it on my whole interior about 6 yrs ago, I wanted all black, hate the stock gray color. But that is me, anyways I cleaned my panels with a good Paint cleaning product that removes Waxes/Chemicals or you can also use soapy water and rinse well. Then I used a Tach Cloth however you spell it, anyways, get it for a buck at any place that sells body work materials and paint. Gets all the fine dust off anytime you paint ANYTHING use that cloth. Then just paint the panels slowly and evenly, light coats until you get 2-3 coats on, let dry and it shouldn't be tacky, it will look good. I have only had to touch up places that my feet scratched and such. Other than that still like new! Good Luck
