Re: Minwax Helmsman Spar Urethane instead of paint?
I've used it on a handful of home made nuc's. It's held up VERY well. That said, the prep was pretty comprehensive. The boxes were tight. Joints were filled before sanding. A light (natural) stain was applied twice over and then four coats of the spar finish. They were made 3 seasons ago and a few have been out all year long (splits, wintered over nucs's, etc.). One of the boxes sat on top of a 10 frame medium upon which sat a cover with a low spot. That nuc has some gray areas that need to be sanded down and touched up but the coating around it is solid. If you don't mind the work, go for it. They look awful pretty sitting there showing their natural grain!
