Designed to produce perfect plugs in heat-sensitive situations where other products fail.
Great for oversize holes; designed to do the job without two-staging.
Plugs holes in thick urethane and resin cover stocks without cracking, chipping or color burnout.
Cures in 10-16 hours at recommended temperatures.
Note: HR™ Hardener is compatible with any ball type, but we do not recommend using it in polyester balls, small holes in urethane, or small holes in resin bowling balls since cure time will extend beyond 16 hours.
