Master Kwik Plug 1 Gallon Kit (Black) A Revolutionary Ball Plugging material scientifically formulated to cure at room temperature in approximately 5 minutes. Compatible with all bowling balls; bonds to rubber, polyester, urethane and reactive balls with excellent results. Because it has the consistency of a free-flowing liquid, it will immediately conform to any configuration. Cures at any temp above 35 degrees F and doesn't require applied heat to speed up the curing. The lack of excessive heat created internally during and after cure virtually eliminates cracking and brittleness inherent in epoxy compounds. 1:1 Mixing makes it simple and helps eliminates waste and over mixing.
