I learned after spending over six hours on the dash bezel a few weeks ago that there is an easier way. On this piece i just used a wax and grease remover (important to remove contaminants before sanding, otherwise you will scratch them into the plastic). Once i wiped it down with the wax and grease remover, i hit it with some 320 to scuff it a bit, then a couple coats of primer/filler found at a local auto parts store. That filled the texture pretty well, and then i just wet sanded it smooth. Once it was all done, i sprayed the blue........then layed down the flames and went from there. Thanks for the compliments.
