RB,
A quick heads up. Its better to stick to one brand on a boat rather then going one to another. I ahve never done it so I can't say from expereince, but have heard its best to attach same material to same material. If its a matter of a day or two shipping my suggestion would be stick ot one brand. Rather then apply one over other.

I won't say its going to create trouble but a little patience may avoid some.
