So, I was putting together a new cooler mash tun, and as I was cutting out the spout the cooler came with, I accidentally put a small slice in the bottom of the cooler. Not even sure if it went all the way through, but I would like to seal it up just in case. The cut is from an exacto knife and is razor thin and only half an inch long. Any ideas for a good way to seal it that is generally food/heat safe?
I really want to salvage the cooler as it was $60 and is 30 gallons. To be used for 15 gallon batches. Can post pictures if needed. Thanks for the help.
