[quote] when i figure a good waterproof one out... will post.[quote]
I have use ext. polyurathane with great results, and use weather stripping around my tops/lids/covers. I also make sure they all have a step style lid to help seal em. I have not had any leak to date, even made a box for my trailer like this.
I dont have a closeup but this is one setup I had 12yrs back.
