no expert here but i'd go along with picking the bondo out with a putty knife. once you get a corner out the rest ought to pop out fine. for the paint, i'd be leary of using a remover as that plastic is old, brittle and expensive to replace. i worked with andy on his side covers and we did well with a random orbital sander and A LOT of hand sanding. then i bought some two part putty filler and did the fill, prime, sand, fill, prime, sand routine. any way you look at it, it's labor intensive so as a psuedo-businessman, watch your hours. don't know if this helps but good luck!
