A 2 part epoxy repair putty supplied as a 'stick' . Break a piece off and then mix the outer with the inner in your hands.. we advise wearing disposable gloves to do this.. and then apply to the damaged area. Workable for approx. 4 mins after working and sets rock hard after an hour.  Some people use this as their 'go to' board repair but most board repairers would suggest that it is a temporary repair product, where watercraft are concerned. Great for 1000's of other repair jobs around the house or garage! 

This is a large stick.. will last for years! 

(PLEASE NOTE. WEAR GLOVES OR CLEAN YOUR HANDS THOROUGHLY BEFORE HANDLING FOOD!
