Krylon Fusion paint for Plastic?

I have used the Dupli-Color Trim Paint. It works good but you really need to do a good prep job. They have it in flat and gloss. I prepped with Prep-all from Klean Strip. Scrub it a few times with the solvent and then let it dry in the sun or under heat lamps. I guess a heat gun would be ok if you don't get it too hot.
