Anyone have any experience using Splash Zone Epoxy, # A-788, made by Pettit? Also a good underwater bentonite for packing the area before using the 2 part, Splash Zone Epoxy, as the final layer. Have an application on a concrete spillway at 30' submerged depth. Discovery & repair will require diver. Small repair area, size of a baseball.

I have consulted with Tech Service at 3M, Sika, they have nothing available to meet our requirements.

Thanks, Mike
