SCORE ! !
I decided I better check it out myself and good thing ! Picked up 2 SS Budweiser kegs last nite.
It was the comment about most Bud kegs being stainless that pushed me into taking a look for myself (thanks dixiedrifter,and x7x).
I took a magnet and a file with me. The magnet would lightly stick to the rolled edges (thanks jdonly1,ugly,BW and rebel).
I also read onlline that if you ran a file on aluminum you would see some of the shaving in the file but SS was too tuff to do that.Anyways guys, thanks for giving me a heads up on what to look for.
I ask cuz' I don't know better...
