Making new stringers and several bulkheads, all being Secondary bonds onto the hull. The top layer that i am attaching to is Woven Roving, Big Weave stuff ( cheap Boat ) any how. What would be proper surface prep and should i use Vinylester as opposed to Polyester, i have heard that it is better suited for secondary bonds.
Surface Prep: Interlux Fiberglass solvent wash, gritty paper to roughen it and then go with Vinylester ????
I am making all my tabs and stringer overlays with 1708 biaxial material, I have used this in the past and seem to have great results.
