The hi-temp red is a little expensive but it will stand up to a lot of wear and tear and temperature if you decide to use a epoxy-plastic. The cheap purple stuff will only last for a few times and it is soft which can allow it to distort.

You probably wont need a mold-release agent for such small parts with the stronger , red silicon. But, you might need it to release your new (red) mold from its wooden form (again, see the blog post on Grilling MY Saba).EDIT: You might use the mold release when making the top-half of your mold, to release it from the bottom half.

I generally use he highest wattage resistor that will fit in the mold or in the case of the glass-tube units, inside of the tube. I don't even stock 1/4 W resistors. New 1 or 2 watt resistors are the size of the old 1/4W units. I would use the highest wattage that fit will allow.
