    I recently saw easy method to form clay for caulking molds. It was on concrete countertop website where they extruded the clay from caulking gun. I put the clay in plastic bag and in bucket of water of approx. 60 °C to soften it, then I put the clay in 50ml syringe and ejected it thru 3mm hole that I drilled
    and used screw to plug the bigger hole. 3mm was just right for 6mm radius. I used heat gun to heat the tool I used to form the caulk, it is easier and it shines better.

    I like the idea of using clay for my radius but it became so tedious to mold over large parts that I gave up. This might solve enough of the application problems to warrant another look. Thanks!

    Wax isn't that easy to use either. It takes me hours to cut, fit and smooth my wax fillets on a simple hatch cover mold. It can be exasperating and expensive, and if the mold cools off like mine do every night you can find your perfect wax fillets have come loose in the morning.

    My buddy uses Bondo for his fillet material and I'm thinking of switching myself...it's fast, cheap and a consumable I already have in the shop.

    Unless I can come up with the right tools for working clay I may be forced to make a change.
