Julie,
WD 40 Specialist is greasy kid stuff. It goes on about like TriFlow. I wipe it all off, but there's still an oily film left, and that seems to work okay here in the desert. In Florida, you'll probably want to leave it pretty wet, and I expect that's an issue with glueing and finishing. I have no experience with Frog Lube. It still seems like the best option would be some sort of wax that dries completely like Johnson's Paste Wax, but waxes don't seem to offer much protection unless they're religiously applied at short intervals. Sigh.
