Plastic prep
New to the forum and have read several threads about painting and coating plastics. Check out urethane supply company there is directions for painting atv plastics. I do custom auto paint and an occasional atv. I have used there products and with the right prep it will hold up to any abuse short of folding it in half. Most products designed for tpo plastic will work, it all comes down to prep. As far as bedliners, if you can deal with the weight of the coating, use a two part mix like actual linex or upol raptor. Stay away from the single stage stuff.
