Thought I'd share this guys youtube channel. To me, he does a really nice job of keeping it simple and using cheap supplies for making molds (furniture wax for release agent and drywall mud for smoothing) pretty interesting.

Good stuff! Now was he a Aussie or a Kiwi? Either way a very skilled craftsman! I personally prefer the galvanized hood!

Drywall mud makes a nice barrier when using polyester over a foam that will dissolve when exposed to polyester, but it has to be very thin. Drywall mud takes forever to dry unless it is a skim coat.

Substitute plaster of paris, bondo, or clay for sculpting a part to pull a mold from (what he was using it for).

Thanks for sharing his technique. It never hurts to add another technique to the ones that have been covered here.

Depends which drywall mud you use, but you are right, typical application is 24 hours to dry. the 20 min set stuff will work too, just harder to sand.

Thin coats of spackle work well - I've also sprayed the blue foam with a light coating of spray glue/contact cement/rubber cement, then wrapped plastic kitchen wrap over the mold & glassed over the plastic wrap...
