Specifically, use CPES - Clear Penetrating Epoxy Sealer. I believe you
can even get some with UV inhibitors at marine supply stores. If you can
not spend much money, you can try thinning regular slow set epoxy with
acetone. It will work but not quite as well as the dedicated products.

Good Luck,


Thanks! I think I'll see if my Dad can use a chainsaw to cut out
the affected area using a V shape cut. Then we can dry the wood and
apply the epoxy.
