i just got an old cooler from my mom to use as a mash tun (planning on just using a bag and not converting it). the inside of the cooler has cuts through the insulation, so i assume wort would get trapped behind there. anybody have experience patching cuts in coolers? i figured epoxy would work to get it water tight, but i don't know if it would leach flavors or anything?
also, the drain cap broke off so my mom just shoved a bunch of surf wax in to plug it up. i think i have seen replacement spouts for coolers, so probably would need one of those as well.
