| + | After the part has been trimmed and the surface has been lightly ground, with any high spots ground down, and any air bubbles opened up, a skim coat of body filler can be applied. Any good body filler that will stick to fiberglass will work. Scrub a light coat into the surface in 3 or 4 directions before applying the fill coat, this will get the filler into the pores better. The part is still left on the foam and plywood buck because it is easier to handle during the bodywork phase. | ||

| + | Now the foam buck can be chiseled out, it is very soft and offers little resistance to removal. The wax and PVA that were applied to the buck are making it easy to seperate the foam from the part. Most of it just pops right off, a blow gun is used to get the smaller flakes off too. | ||
