the material you mention is appropriate (BTI ?) but keep in mind that the secondary bond of polyester is okay, at best. I recommend epoxy for this application but make sure that the material you use is compatable. Don't get too hung up on "which material is strongest" as you should match the "strength" of what you have and anything but straight matt is strong enough (and it is typically NOT compatible with epoxy). Let us see what you are doing! - Mark
