well, there's a good cheap idea! ...just the kind i like
I just added my own vent to the vent less cans. Bought some metal valve stems at the auto parts store, drilled a hole at the top rear of the can, and removed the valve core. Hardest part was getting the valve to feed up from inside the can. I dropped a string thtough the hole and fished it out the spout opening, tied it around the valve, pulled it up and screwed the nut on.
