Yeah, I was surprised how well it works too. I usually do that with a 3" jerk bait mold and 3" craw mold. I mark my molds top and bottom and leave enough foil to fold around the bottom part of the mold. I then take the top part off, the top will peel away but usually it leaves the bottom behind with no issues. Just take the foil off slowly and shoot the top color. Its a great trick for molds that don't have lam plates or if you don't wanna pay extra for the plate.
