i've tried it myself and in the long run i would say it's better to get a proper sized seatpost.
thing is seatpost/seat tube take on quite a lot of stress. try riding around for an hour and take that seatpost out. you'll realise the beer can's been grinded down a bit and it'll eventually wear out.
use copper grease.
