Sand blasting would tear through plastic. I recommend sanding it with sanding sponges working your way from the rougher to the finer grades (home depot) then wiping it with mineral spirtits(paint thinner) or laquer thinner to make sure all oil was 100% removed. If you paint an area and the paint seems to thin out and spread unevenly then there was oil underneath. Hope this helps

you can have it soda blasted or plastic blast it. it doesnt damage plastic if done at low psi and removes everything. recomended psi for blasting platics is 40psi and under
