I've looked over the new cans at different stores. Good luck finding something you like.
I have the older ones with the semi locking yellow cap on the black spout. The pressure will build in the can and blow the cap off. How many of this style can do you see around town without caps? I have 6 5 gallon cans, 2 2 gallon cans and 2 1 gallon cans, but only 4 caps. I was thinking of putting a piece of baggy over the spout, adding some caulk to a bottle cap and pressing onto the spout. Let if cure a few days.
