best exterior varnish
Any product you choose will have to be re-done after 5-6 years. Cetol and Varnish have to be maintained. Cetol''s claim to fame is that you don''t have to sand between coats, only at maintenance coats. However, I advised a light sanding any way to clean out the bugs and other bumps between coats for a better looking finish.
I live in Florida and the sun and pollution are brutal. Texas is worse. Keeping the boat rinsed helps a lot.
