Sealing Cans is easy.
We sealed a 190 cans of wheat and legumes using a #10 can sealer belonging to the LDS Church. Five of us were able to seal these in just under two hours. The cost of the cans is $1.00 each plus tax. The following You Tube video shows just how easy it is to use the can sealer. The finished product should be good for 25 to 30 years.
