Thanks for all this advice.
Tim, Do you recall if you used a tight nap roller? Seems that would be the choice. And, yes, your recollection of the Mar-K system is correct except Mar-K applied 3 coats of POR15. I still have to cut(round) by sanding the board edges and the weather may not cooperate for POR15 application, but I'll post how I made out when done.
