What is the best way to preserve a can?

Question

My sister is a HUGE Monty Python fan. I bought her a special edition can of Spam with the Monty Python theme on it. When I tried to bring it from the UK to the US I was almost arrested in customs!! (Spam is considered a meat import!! Go figure!!) ( Is spam really meat anyway?)

Anyway..after searching once more I have found another can. I now know to remove the spam meat from the can, now I want to preserve the can from rusting. Any suggestions?

Answer 1

Clean it and spray it with warnish or other incolor lacquer

Answer 2

You could use a clear varnish inside and out that might work. Where did you get it from? My brothers been after one of them for ages.

Answer 3

Put it in a freezer.

Answer 4

I didn't think cans rusted these days!
