bumper stripping

plastic, paint, bumper, rest, sanding, grit, orbital, half, life, hours, damage, bare, brake, fluid, stripping, safe, backside, stripper

the bumper paint on this car has to go, right down to bare plastic. brake fluid didnt do it, plastic safe paint stripper cant get through the paint and still seems to damage the plastic on the backside, so i dont want to use it... sanding with 80 grit on an orbital would take the rest of my life (3+ hours in im half done one of the two) what can I do?
