Science is true whether you believe in it or not.
I have a procedure for fixing seams in fiberglass gas tanks.
I use a thin cutting disk on an air tool to groove the joint where the leak is. Then I apply vacuum to the tank. With a cotton swab, I clean the joint with acetone. The idea being that the vacuum will pull the acetone through the joint and clean it. Then, while maintaining vacuum, I apply liquid epoxy resin to the joint. The vacuum will pull the epoxy into the joint.
