Basically it’s like “the Mix” but for canvas ... allowing all the fibers to be saturated with glue ... For me it was the unsized fibers that held water later ... I really think with the drip edge installed , you won’t have to do much of anything as water will not get onto those areas , not from rain anyway .... Water splashed up from the road , that’s another story ...But on my all steel cargo trailer , the board floor is just raw wood underneath and looks in fine shape ... Curious !
I thought I remembered reading somewhere else that paint doesn't stick well to TB2. If the canvas is completely saturated with TB2, would you then prime with Glidden Gripper before paint?
