Hi guys, So far this site has been the best as far as giving advice. I'm down here in Baton Rouge, LA. My Coldspot Freezer crapped out on me so I'm turning it into a fine smoker. I'm just about finished gutting it, so here's my question/problem that I see forthcoming. Once I put the insulation in and then the inner box back in, (I had to take out the edges holding those two in because it was made of plastic) what can I use to seal the outer box, insulation, and the inner box so the insulation is not exposed, and so I can shut and seal the door?
