Painting a logo, sealing for sea use
I'm currently working on a small woodworking project that includes some stuff I've never done before.
I want to paint a small logo onto a wooden box, then seal it/protect it for use on a boat. This would be given as a gift to a relative who does a lot of sea sailing, and the box would be a nice item to have below deck (not directly in contact with seawater).
The logo would be a single color, probably black, custom designed and around 2 inches square in size. There would be a little bit of detail involved, so I thought a stencil might be the best way to go, but I've never done that before. Is there a simple stencil system that would work well for my purposes, or is there a better way to go?
The second thing I'm wondering about is the best way to seal up the wood after I put the logo on. I've done some work with polyeurethane, and I would guess that would be OK, but I'd love to hear any other suggestions.
