fish well and cooler

[bassarama]

You loose lots of cooler space if you insulate from the inside, I wonder if there's a way for you to pour insulation foam on the outside of the boxes walls and insulate those nice size fish boxes.

I have a CeC which has a non insulated fish box on the forward deck and the livewell which is not insulated either. I can't see how it would be possible to insulate the outside of my boxes/livewell without cutting the deck and undergo major surgery on the boat.

Has anyone done this before?
