I'm about to build my first smoker and am going to do it out of 3 55 gallon drums, I picked up some cheap used food storage drums for $10 a pop. the drums held glycerine. Its a simple polyol (sugar alcohol) compound. My worry is that after removing removing the tops I came to find out the drums are painted inside with im guessing is a non toxic paint to not allow the alcohol to come in contact with the medal of the drum. I have no idea what the paints name is and at what temp it will fail and I don't want start building my smoker just to find out I made a poison smoker.
any insight would be great.
Here are pics of the drums.
