Is a pressure pot required to cure castings made with TotalBoat Cast N Turn clear urethane casting resin?

TotalBoat Cast N Turn clear urethane casting resin does not need a pressure pot to harden, but a pressure pot is required to eliminate any bubbles while the resin is curing. The high pressure also forces the mixed urethane into any crevices or textured areas of a mold to ensure the best accuracy and detail when casting.
