#1 establish guide lines i.e. center line, ribs, lumps of clay defining
clearance above existing parts, fill voids with cardboard, crumpled newspaper
ect.mix 2# density foam and pour in small quantities controlling spill with
taped
in place paper, or get an insulation company to spray it. shape with saws,
elec.plane, curry comb, rasp, "cheese grater" finish with sandpaper, when
close,
thin 20min sheetrock mud and spray with your favorite gun pressure pot works
best, sand -spray-sand spray ect, apply a thick coat of partal #2 wax spray
multiple coats pva mold release let dry and lay up glass, Centerline is most
helpful for establishing semetricity, you can make half outside templates by
pushing cheap thin rigid plastic into foam and tracing. Thanks Jack
