I am getting ready to paint my interior but have a question. On my truck, not sure how it is on other rangers, I have a piece of soft vinyl on the top of the door bout the black handle, arm rest. i will be using an adhesion promoter, SEM Dark Graphite and SEM Landau black paint. is ok to paint that part or because it is soo soft and pourous it will mess it up? I would like to paint it but if it will screw things up then I won't.
