What are you using to waterproof the inside of your DIY stand?

I have my frame made, Gonna buy the plywood for the skinning. I am building it for a RR 40G breeder with a 20G long sump (which I made yesterday). I wanna buy the stuff for waterproofing the inside and the plywood at the same time. Gonna skin the outside with birch and prob stain ebony. Thanks guys. Can't wait to post pics.

Kilz is great for painted interiors because of the stain blocking properties or you can use any oil based primer and paint. Otherwise any urethane based lacquer will work. The marine stuff is great and they have a super clear version that doesn't yellow.
