Platinum cure is actually testier and more prone to not curing - plastisol, alcohol will inhibit cure as will freshly coated epoxy.
However, it is the best silicone and lasts longest.
MoldStar30 is what I use - wooden masters lightly sprayed with krylon crystal clear.
Put a thin coating on your bait, then wait 10-15 minutes and pour a thin high stream into the corner of the mold box - this helps minimize bubbles.
Silicon molds typically need a couple pours of plastisol each session before they start to come out shiny and dent free. Just remedy the first pours and mix in with new plastisol.
Moldmax30 will work too if you are using plastisol baits to make your mold.
