Getting close to varnish stage, and was just wondering which would be better to use, the Polyurethane or the spar varnish. I am going to use the System three products, since they are local, and have used their epoxy, but just not sure what the difference is. Which is easier to apply, stand up to abuse? I just have no idea at this point, but have used the poly in the past on other projects.

Thanks.. Ric A
