Brilliant! and nice photography.I have a smaller Coleman Marine cooler that I did some of the 'upgrades' to; I find the Marine coolers kind of like the Xtreme models - a bit better than run of the mill coolers but still cost effective. They also seem to be insulated lids which is a bonus. This one smaller cooler has those can holders in the lid though - which we all know makes a thin area of no or little insulation. So I 'fixed' that:
Had some foiled faced rigid insulation laying around - 1" I believe - from a house project. Cut into that and made insulated fillers for the can holes. Perfect thickness. Sealed the edges with silicone.

Picked up jack nuts [see post #45] and countersunk stainless machine screws [hex head] and a white polythylene cutting board.

Cut the board to fit the raised area of the cooler lid which also covers the insulation filled can holes.

Drilled the corners of the board and cooler lid to get holes aligned; installed the jack nuts in the lid. Countersunk the holes in the board for the machine screws; ran a bead of silicone around the perimeter and assembled it all.

Now, no thin insulation spots on the lid and I have a small cutting board.
I don't understand the physics or chemistry of this get but it definitely works.
