My bulk tank has 5-10 pin hole leaks in the bottom. I tried soldering them this morning, but the solder wouldn't stick to the tank so I'm considering some kind food grade sealant or caulking to seal off the holes. Any ideas?
Grainger sells this which is FDA approved, but for indirect contact only. I didn't find anything else from them.
