Thanks. The problem I have right now is the rig is custom made and isn't square. That creates a problem because I had to custom fit the decking to fit the truck bed. Now it only goes in one way or it doesn't fit.

As I wrote before, I've never done wood finishing so I learned a lot along the way and made mistakes. I'm going to try your method this weekend on a couple of scrap boards before I screw up the finished decking. Thanks for the recommendation.
