O'Neill Wetsuit Repair Cement
This O'Neill Wetsuit Cement comes in a four ounce can, with a brush in the cap. This stuff is the real deal - a thick goopy black substance that's designed to fix tears and holes in neoprene. Since it is black, it will blend in with your wetsuit! Sets up very quickly. Works well on smoothskin coatings.
Shake well before using. Apply cement on both edges of damaged area with applicator brush. Allow first coat to dry for 5 minutes. Apply second coat and allow to dry for 10 minutes. Press together firmly for long lasting repairs. Make sure you keep a window open!
