i did mine with duplicolor also adn it does chip off sometimes.... ive re-done my interior twice. you should get OEM paint and do it to match your car's exterior color.... the only thing is that it's more expensive, so its only good if you do it when you have another body part to paint.......

 

I just picked up a can of satin black Krylon plastic paint. I'm gonna see if I can get a hold of a piece of interior trim from a scrapper and paint it to see how it turns out just in case it looks like crap. I was thinking of clear-coating the trim pieces after they're painted to give a little bit of extra protection and shine.

Thanks for the advice.

 

Paint might be better, although that looks good in the pictures. PM me and I'll give you some instructions on good interior painting.
