Answers to questions I think of me that came up....
I varnished my car apart to do ALL the sides and edges including the plywood edges. We made our own plywood by starting with aircraft grade 1/8 " maple and veneering it up (in a big vacuum press) to the proper thickness. If you varnish one side of a piece of plywood it will warp it due to the tension created when the varnish or whatever you put on it dries. This is true of any wood, like cedar siding. The Z-Spar Captains I used dried overnight and was ready to sand and recoat the next day. Sanded to smooth and give tooth for next coat, not down to bare wood.
The first coat of varnish was thinned down 50% with Turpentine to penetrate the raw wood, the rest was full strength. (Paint thinner is synthetic Turpentine)
Rick Mack is a fried of mine (McCloskey is his last name!) , but the person who taught me to varnish was the late Jerry Veley from Oregon.
