I have built a Glasair 1 TD and do have a little experience in making one off
parts and parts from scratch...I use the west epoxy system...you can order the
kit with the proper proportioning pumps from aircraft spruce...the west system
dries clear and usually cures overnight at 70 degrees and come in pints quarts
or gallons I believe..you can order the catalyst with fast or slow set formula
depending on the temps that you are working on and the pot life you need....its
by far the best stuff I have used and the shelf life is years. As far as mold
release I have used automotive wax with good results...its releases fine and
cleanup is easy...most people building glass composite aircraft so not use gel
coat...its heavy and messy and there are primer fillers that do a better job and
provide better paint adhesion....when glasair first came out with their kits
builders found that the only way to get the paint to stay on fiberglass was to
sand the factory gelcoat off to the raw glass and prime and paint from there.
For fillets and corners I used automotive body filler (bondo) or milled
fiberglass fibers and resin..depending on the strength and location...bondo
worked great and makes nice fillets when have to build many layups for big jobs
and milled fibers (make your own by cutting scraps of fiberglass cloth into
little pieces) for little parts that cannot have or will not need many layers
of glass such as fairings speed cuffs...ect...I hope this helps a little....work
with the little parts at first and I am sure you will find that this is easier
than you thought....Gary
