Wondering what people would recommend to (at least partly) insulate my icebox
It's a top-loader, with a drain in the bottom. Previous owner cut a hole in the side to add a cooling
fin (which works of the shorepower) but this only seems to make the ice last a few hours longer.
I think this issue is that the box is basically a fiberglass
might improve matters, but what and how? Don't want to put anything on the inside of the box because that strikes me as a mildew trap.
Are there spray-on products that might go on the outside? Or something else?
