Interior painting?! Help?!?! Please?

[chicka]

Ok, I have a slight dilema here. And I need help!!! AHhhhh!!! Hehehe. Ok, my fiance is driving me nuts, but I didnt say that. He is painting the interior of his S10. And it is not cooperating how he would like it too. He took off his door panel, sanded it down and cleaned it with denatured alcohol. Then he spray painted it. The brand paint he is using is Dupi-Color, it says it is for the interior vinyl on vechiles, but it was cheap only $3.99 (I dont know if that means anything). He put on about 3-4 coats. Then he sprayed Rustolem over it to seal/protect it. It looked fine after that. But the next day dun dun dunnn...there was a bunch of little bubbles and it had cracked. Also you could just peel the paint off like it didnt bond to the plastic. Now my questions are : Should he have primed it before hand? If so what brands are there that we should use? Could it be because there is residue of the denatured alcohol on it? Could it be the brand paint we are using? I have only seen a couple other brands. What brands would you recommend?
I would really apperciate any help. I have been looking ALL over the net for specif answers but they are all so vague. I hope I can find the help on here. I would like to know so I know what to do when I start the interior of my car! Hehehe! Thanks!

I say have him give up on it, it's a waste of time and money and it looks tacky if done wrong. If you really want it done right though have a pro do it.

personally, i used 3 coats of primer, sanded with 1000 grit before adding each coat, i used 3 coats of color, and i used 2 coats of clear, thats only on the plastic pieces., on the vinly pieces, i took a can of my spray i was using to a upholsty shop and they mixed me a 1/2 a gallon of vinyl dye to color match the paint on the pastic piecesrule number one when painting interior....never spary anything that has a flexible material or else it will just chip off, you will ahve to dye those pieces like i did, here is a pic of mine, im still only half done

Im thinking about doing some of this kind of work on my Sentra. Its not such a big deal if I mess up, since its just a beater anyways.

What brand of paint did you use? I like the color in the pics, looks great!
