Two thoughts that may even be related:

1. one of the folks at one the marinas I dive at has done a lot of
fiberglass work as a job. He said that the Git Rot product penetrates the
wood even when wet and drives the water out. He really liked the product.

2. When I was looking at the CPES I talked with one of the chemists at
System 3. He said that their low viscosity product penetrates as well or
better and provides about 3 times the coverage (perhaps the name of the
company?) because it is not thinned with solvents. I am aware that he
wanted to sell the product but it is something to think about.
