With all due respect- The subject of this thread is a method to glass some floats. The water based clear stuff is very appropriate for the application. It does't stink, dries very fast, sands great and accepts primer and paint as good as anything. Please don't confuse the fuel resistant properties question with the original question in this thread. The top coat OVER the glassed surface is ALL that matters unless you are going to fill your floats with fuel. I will also used the method for glassing the foredeck on a bipe I'm building.
