Re: what is the strongest fairing putty
what is a little hook?
there is more to this question than fairing puttys.
what caused the hook?....was it the rollers on the trailer?.....that means that the flotation foam in your boat is wet and it has lost some of its anti crush.
however...
poly fair is a very good product. it is on the bottom of my hull. when going past the thickness that the manufacture reccomends, do a wrap of fiberglass over top of the putty.
i am assuming you are just doing trailer bunk "dips" in the hull.
if you are......chopped strand matt in sucessive layers will build the area you want and if applied properly will be as strong as steel.
the new fiberglass can be ground till flat then apply gellcoat in a standard gellcoat repair process.
