I used it on pp black plastic 2 piece rear bumper. Paint stripper and a light 400 sand after then set in sun to warm up, 25c sunny day then good wipe down with thinners then iso. Two wet coats and 3 hour dry in sun. Normal primer will then stick, pretty well it seems. Blade putty over primer also looks ok. Redo plastic primer if you rub back too far to black plastic keep layering if need be. A good cook in the sun in between coats seems to make it stick good and get feathering on edges not peeling, peeling means not clean enough. Flexing in between coats does not pop the fill out, yet. Two cans more than enough, it covers well if not over done. Get it wet and it looks to soak in ok, like painting mdf. A good 30 minute can shake highly recommended to stop clogging and use a can gun.

Works very well

Quality product at a great price.
