Will peal and stick tile adhere to metal?

it will but in time it may peel up in the corners - look on the box of the tile you are planning to use or go to the mfg. website of the tile to see if they recommend a glue

Check the instructions..some may not be recommended for metal. If you do attempt this, I would use denatured alcohol to clean the surface to be sure it is completely free of any oil, or film left by soap, rain, etc.

yes it will and it will last about the same as floors. Just remember that the adhesive is heat sensitive and metal conducts heat. If the metal is near a heat source it will weaken the glue and destroy the work you do.

It should stick fine to metal.
