: I would love to find a way to do it with out wrinkles. The problem with a
: shrink material is that the male mold has indentations in the crotch area
: and shrinking would bridge that. That's why i used the Vaseline which is
: sticky enough to hold the Seran wrap in place. One time I tried auto wax
: and put on several coats and the last coat was literally smudged on thick.
: I let the epoxy/glass harden over night. That was my first experience of
: panic since I could not get the seat off the mold. The tinniest fissure or
: imperfection in the mold will trap a drop of epoxy which turns to stone
: and the casting is locked on unless you "break" it free. I
: thought my mold was as smooth as glass too.

Btw, I only use mold release wax for this, it's pure carnuba and most car waxes that say they are have additives that may effect the release. I bought a can of "Meguiar’s Mirror Glaze 8 Maximum Mold Release Wax™" about 15 years ago and still am using it, lasts a long time
