    NO, it's getting wet because the joint is too tight and with heating and cooling cycles it expands and has nowhere to expand to and is lifting allowing water to get underneath......as shown by the black drip line in the lower right bung. I would've sliced the joint open more and then filled with the wood colored putty designed to fill joints. At this point in the game, I would try recaulking where it meets the fiberglass.

    I bought Rust-Oleum 207008 Spar Varnish. And I have a wooden sign (looks like the American flag) and would love to seal it and place it outdoors. Does this product turn the wood an orange color?

    No idea. I've never used Rust-oleum varnish, but for what varnish costs I'd rather use a marine grade varnish such as interlux.

    The reviews I've read talk about short shelf life, thinness requiring many more coats, longer drying times and UV protection not lasting. Although I like Rust-Oleum products for metal I have to agree with J on this (although Interlux wouldn't be my first choice either as I've had bad experiences with their products).

    What kind of wood are you looking to finish?

    If it's not water-clear in the can; it will add color. Some varnishes are amber colored in the can, like Schooner Gold, and some are very dark, almost a black coffee color in the can, like Man O' War.
    The only wood finish I have used that is clear after application is water-based. It looks like non-fat milk in the can, but dries clear.
    Bar-top type epoxies may work, but be sure and determine the UV tolerance if it is outdoors, or even near a window.
    You may be best off with an automotive clear coat.

    I've been varnishing since a teen in the 80's. Anything from big schooners to Superyachts. Every job is different, each finish is for the boat's use. There is no right answer without knowing how the wood is used.
