x2 that was my first suggestion! also not sure about inside but once properly cured and completely aired out I would THINK it would be ok but not for a fact. I've used the krylon for plastic spray paints on law furniture before and as long as you use thin coats and allow it to dry 100% between coats it holds up pretty well. if its not properly cured between applications it tends to bubble and peel fairly quick. not sure if it would hold on plastic but you could always paint it with the krylon for plastics and then clear coat it with a polyeurothyne. I know people use that to seal wooden enclosures. just a thought....
