The Cetol Marine Light I used was a one part application, didn't need to buy a different second can. The recommended number of coats on the teak is determined by the teak being new wood or old weathered teak. Naturally, my teak was very old weathered teak which took some teak cleaner, and then sanding with a ROS. The bilge/battery door by the OB engine well had a teak plywood center panel that had delaminated. I found a boat lumber place in Marathon FL. that had new teak marine plywood that you could buy by the square ft. Believe me, you dont want to buy a 4x8 sheet of teak marine plywood. Buying by the square foot is expensive enough!!! It's almost as expensive as starboard!!!
