To ensure the best castings possible, with the least amount of bubbles, the individual TotalBoat Cast N Turn components can be placed into a vacuum chamber prior to being mixed together. Dispense the proper amount of each component into separate mixing cups, and place them into the vacuum chamber. Inducing a vacuum will remove any bubbles before the mixing process. The more vacuum that can be applied, the better the results will be. Immediately after mixing the two Cast N Turn components together, the mixture can again be placed in the vacuum chamber for another 2-3 minutes, if desired. After this period, the Cast N Turn should be poured into the desired mold and put in a pressure pot before the working time has run out. Cast N Turn should only be cured under pressure, never under a vacuum.
