Wow, my garage smells like an Italian salad bar!! :biggrin:
Just checked on the mold and the outside has set up nicely. Can't wait to open it tomorrow afternoon to see how the rest of it has done.
Charlie - I think I'll try using some shellac to seal the mdf and see how badly the silicone sticks to it. Will try a small sample first. Shellac creates a pretty hard and slick surface so the silicone may not adhere to it. May also add some furniture wax to make it even more slippery. If that doesn't work I'll try some mold release. I'll do anything to get out of having to put that poly wrap stuff on each time I want to make a mold. It's a PITA to put on and get the wrinkles out before putting the silicone in.
BTW, I sized my form so the entire mold has 3/4" sides and bottom. Assuming it will harden correctly, it should give me plenty of sidewall strength so they don't sag or bow out from the weight of the PR.
More pictures of the results (good or bad) later tomorrow...
