Greetings, There have been a lot of really cool looking cans being released over the years. I would like to know, has anyone done anything to preserve cans? I was thinking of opening them with a can opener on the bottom and filling it up with urethane or something, then closing the holes back up. Has anyone done anything similar before? I have seen people make cans into shift knobs before, but I have no clue what they fill them with. I know this isn't a beer can, but you get the idea. Thank you in advance.
