I don’t use the sealer. Works perfectly without it. I understand that to do it by the books would involve the sealer, but really if you’ve got a well polished surface, after a few coats of Frekote, nothing is gonna stick to it.
Agreed. The sealer is really to seal porosity in the mold surface. On the metal molds we would heat them up to open the pores and then seal them… not sure if that’s really necessary? But you just follow procedure right?
