i havent done the block yet, but tried heads,intake and covers.
how much release spray are you supposed to use, and it says to dry completely. is that correct when doing small items?

A little bit goes a long way, I buy my ease release in the bottle rather than the spray, and I brush it on with a nylon bristle brush. spray or bottle, you should brush it out regardless it helps it get in the nooks and crannies, and spreads it out evenly. Let it dry..but it doesnt take long. when Iput it near a warm spot.

I use the Ultra 4 paintable mold release. Despite what it says, I spray it in brush it around and let it set for about 20 minutes before pouring any resin in. If you don't allow it to gas out first you will make parts that will be rubbery and never cure properly. You might be able to call them for a free sample can. That's what they used to do but times have changed in the business world.
