Is it neccessary to keep appying release agent (Man's 2910) to the inside of the rubber mold (dragon skin)? I've made my first pour with smooth on 300 and looks real well.How many pulls can i expect to get off of this mold? Thanks, James

While Mold Release is not exactly nessasary to use with silicone molds, it does without a doubt extend the life of your molds by limiting surface stress when pulling cured castings from the molds.
It will double the life of some molds. The amount you can gte out of a mold is kind of conditional.
How hard it is to remove the castings, release spray, the type of silicon, ect.
50 sets is not unheard of, and more sometimes.
