    Hard to keep bubbles out.

    Posted by Jody on Jul 2nd 2020

    I've tried vacuum, pressure and tech support. Watched every video and read everything. It's difficult to get bubbles out. I have yet to make a mold without bubbles and on third kit. The mold is also very stiff, so hard to use a 1 piece mold with plat 55.
