Can this Pro-Seal be used on plastic gas tanks?
Per our tech: This a tricky one. The manufacturer doesn't recommend it, but builders have used it as a sealant for fuel probes and gaskets for years. The manufacturer doesn't have any lab tests to show how well it works or doesn't work on plastic, so they will not recommend it.
What is the working time of this Pro-Seal sealant? I need something that has a 2 hour work time.

Can Pro-Seal be used for fiberglass tanks?
The manufacturer has not tested this material on fiberglass, so they can not guarantee how well it will adhere, but in general, if the surface is contamination free and has a smooth surface, it will adhere. We suggest contacting whoever made the tank, and ask their suggestion for sealing cracks, or pin holes, in the tank.
