Auto body repair & detailing: interior Dye, vinyl paint, vinyl dye

Question
i was wondering, i bought some interior Dye from a local part store. the dye dried just fine to the hard plastics, but the door panels are still very tacky. why is this? why will the paint not dry to the soft material? or does it just need longer time then the hard plastics? i didnt use any kind of primer cause the dye didnt say to use. it just said to make sure that material was cleaned by a wax and conditioner cleaner and thats it. can you help?

thanks

Hi Paul,

I imagine what happened was the quality of the dye you used was poor. If I had to guess what caused it to be slow drying on the hard plastic parts it would be that the color wasn't covering very well so you put many multiple coats on to cover without dry time between each or you put on a very heavy coat. My best advice would be to use a good quality interior vinyl spray. I personally use SEM color coats for vinyl and plastic and SEM Classic Coats for leather or pleather (replica leather).
