Sheeting the Wings

[Van - E-Mail LIST]

George,

There is no hardener in Pro Bond. I use it all the time , and I live in
Tampa, FL. It's a polyurethane glue, and it uses moisture to cure. It foams
up as it cures. Normally I use it on the 35 or 40% wing panels that I build
for the Carden stuff. It's fantastic. Excellent penetration in the foam, and
once it is on, the skins are not leaving the foam . . . .ever.

My workshop is a 24' by 40' that has garage doors that open on both side for
breeze, or plane access ( the 40% stuff requires it ) I do my sheeting in
this building, and it works out great. I use a very thin coat ( spread with
a BONDO spreader ) on the sheeting and the foam. On the 40% wings, I then
put about 200 lbs of block on them over night. ( The panels have a 1/2 thick
piece of plywood on the top and bottom of the panel. The blocks are added to
the plywood, not directly to the panel.

This works REALLY well
