White oak is fine as long as it is sealed on every side. Epoxy or CPES is excellent for this, but it has NO UV protection. If you use any epoxy product, coat with a UV stabilized varnish or polyurethane after the epoxy application. Check out James Town Distributers for a product called Total Boat Penetrating epoxy. Top of the line stuff I use for all my wood boatbuilding projects. It can be mixed and cut 50% with Acetone to give the ultimate in penetration in wood. Use this with Epifanes Boat polyurethane and you will never have to do it again in your lifetime. Of course if you want to do it on the cheap, and don’t mind doing it every 2 years or so just hit up your local hardware store and grab some exterior spar polyurethane. NEVER use pressure treated wood on aluminum. The copper sulfate used in the treatment process will eat holes in your aluminum in as little as 2 years.
