A couple more data points for you *do-it-yourself* aficionados:

1. Re-establishing the original airfoil can be done by making some *quick &
dirty* templates, before starting. Wax and PVA (mold release) several locations
along the leading edge, say every 24 inches. Now make cardboard templates for
these locations, nothing fancy, just roughly the shape. With the L/E up, lay on
about 3 strands of glass rovings around the template locations. Next, pile on
some epoxy flox and shove your cardboard templates into the goo. Pop them off,
when cured and you have some exact replicas of your original leading edge
shape. I carry my templated back about 3 inches, as this is the most critical
area. Everything else is contouring to keep a smooth shape, both spsn-wise and
cord-wise.

2. You will need a good water trap in your feed line coming from the
compressor. I have used the *toilet paper* trap for years. It employs a roll of
toilet paper as the filter element. Just replace the roll before each major
operation (each wing) Some red-neck repairmen have even been known to dry out
the used rolls and then employ them again, for their original purpose. If you
don't have a good moisture trap, your spray gun will spit out little water
drops and they will show up as little craters on the product.
Have fun and remember, Everybody's got to be doing something. You have just
chosen to sand for the rest of your life.
