suggestions for strong & water proof finish

Hi, I am new to the forums and to the whole art of selecting the right finish.

I am building a storage box for my fishing gear. i'm over having gear strewn around the house and shed. Its going to have a number of removable compartments to be taken fishing with me, so i want a really robust finish thats also going to provide water protection. Im building it out of plywood with kauri inlays.

I want to stain the plywood to give a darker finish but i havent got a clue what would give me a strong and lasting finish. Any help would be appreciated.

If it is not exposed to too much sunlight, use epoxy. If it will be exposed to much sun, use a good marine varnish. To get the best water protection and UV protection, use epoxy and overcoat it with the marine varnish.

Cool, thanks for that, are there any types of epoxy i should use or any brand that is best.

Two good brands are West Systems and System Three.
