techniques for painting dashboards/vinyl

Well i painted the interior of my 91accord and it is not an easy task. However, it is not hard but it is time consuming. The fist time i painted the interior i did it without removing most of the parts but that did not last to long because the paint cracked pretty easily. later i painted it again.  This time i sanded everything first then i cleaned with thinner, then i added the promoter, paint and clear coat. I also wet sanded the whole thing after it was dry. And i have not had a problem since. It took quite a while since i only had little time to work on it. However, as much time and patience you put on it you will get out at the end. I spend so much time because i wanted it to do it right.  99civivtrbo
