I have been trying your finish methods and find it very beneficial. I wish to know if the same procedure will work with Spar Urethane and Spar Varnish.
I am glad it’s working out for you. I have never tried it on Spar finish. However for anything that I used to use exterior spar finish, I have gone to Nova, Exoshield because it holds up better in the harsh sun and weather conditions in the south
