Before making a batch on my new system, I wanted to make sure there were no leaks in my three kegs (HLT, MLT, boil). Turns out the keg I planned on using for my MLT has two pin sized holes on the bottom. I've put JB Weld on the outside of the keg to plug the holes, but I am not 100% sure I want to risk the possibility of something leaching into my mash. I've seen another product "Water Weld" that is food safe and am considering putting that on the inside of the mash tun. Am I worrying too much or is the Water Weld something I should use as well?
