Get PVA at http://www.aircraftspruce.com/search/search.php . I also
searched Wicks' site because I KNOW they have it, but after about a minute
of search through everything from tailwheels to foam, I gave up and found it
instantly at AS Basically it's used as mold release agent. Wax the mold
with mold release wax, then spray a very light dusty coat of PVA (if you put
it on wet it'll just bead up on the waxed surface), and then once that dry
coat dries, you can put on a wetter coat or two to form the film. Then
layup your cowling or whatever, let it cure, and the PVA will pop apart (or
will dissolve if exposed to water). Never heard of using it for sanding
purposes, but if Lee says it works, it probably does...
