Monday went not as well as planned, but still, somehow, better than expected. Got about half the mother mold done in Plasti-Paste. I wanted to add another layer of it on for reinforcement, but I was running low, so I decided to try out my trial kit of Shell Shock to slather on top of it. Shell Shock is weird stuff. For anyone wanting a thicker, more brushable resin than Smooth Cast to use for casting, I think it would work very well. As a mother mold material, though, I don't think it's very suitable at all! Part A is the normal brown liquid (maybe even the same stuff as part A of Plasti-Paste), but part B is nasty stuff. My little tub had been sitting for a few months and when I started in mixing it seemed okay... until I got lower into it with the stir stick. Apparently, it had settled to form some kind of clay at the bottom. It took half an hour just to finish mixing part B before I could mix the two together!
Then the fun started... It's much thinner than I thought it would be. Applying it on top of the Plasti-Paste was mostly disastrous. It ran everywhere and dripped all over the place. On its own it is extremely brittle, but I think it might be okay for how it is. It seems to have strengthened up the thinner parts of the Plasti-Paste and, in turn, the Plasti-Paste is helping to reinforce the Shell Shock. It's certainly ugly, though, and difficult to work with for this purpose. Maybe if I had gone with Shell Shock and followed that up with Plasti-Paste instead of the other way around?
At any rate, I had JUST enough Plasti-Paste left to do the other side with a layer as thin as the other side, so I think I'm going to try my hand at the Shell Shock again for some extra support. Now that I have mother mold on both sides, I can handle it a little less delicately.
Pics to follow. Thanks for looking!
