Homemade Fish Box?

Haven't tried it but am thinking about doing the same on my center console. I currently have a 72 qt in front to sit on but would like something that goes from the console to the raised front step and put a large cushion on it for better seating up front and more ice chest capacity. If you build one definitely post some pics

I hope you find a way to use Great Stuff in it.

1) acquire a few sheets of 2" rigid roofing insulation (with paper backing, not foil)

2) cut the sheets to the size box you want (bottom, sides, top)

3) assemble the pieces using nails to temporarily hold it together (just push the nails in). it helps if you build a jig of some sort to get it square)

4) on the inside, use bondo or thickened epoxy to fill the inside joints and give you a rounded joint. on the outside, sand down the square edges to round off

5) lay up inside and out with chopped strand mat or woven roven and general purpose epoxy, several layers. you'll want to reinforce the edges and seams with strips

6) lay up the top, same way, both sides

7) paint the inside with food grade paint. either pait or sand and gelcoat the outside

8) affix SS hinges to the top and box, i usually thru bolt them thru a backing plate

9) glue a foam strip around the inside of the top where it hits the box as a seal

10) stand back, crack a beer and admire your cleverness

West System ice chest

I'm planning to do one soon. Found these "plans" the other day. I'm not planning to do plywood on the inside, just outside for some rigidity. Fully expect this to cost way too much and be way too heavy, but want to learn how to lay glass and make it look nice.
