Well, I guess I am in the minority. I HATE those so-called self venting cans. First time I used one, the gas had expanded and when I loosened the cap gas came out all over my hands. Kinda negates the purpose of reducing air pollution when the gas spills on the ground where it evaporates. They don't pour worth beans. One of the stupidest ideas I have seen in years.
So I looked around and found some vented cans. I have 5 or 6 and have yet to loose a vent cap. I have a 3 or 4 that are the 2 handle kind and 2 that are rectangular, about 16" long, maybe a foot wide and a foot high, made in Canada. Low enough that they don't tip. Only one handle, but they work great & after considerable cogitation I came up with the bright idea of simply putting one hand under them to support the weight, thus negating the need for a second handle.
None of these leak. Haven't lost any vent caps. They pour well.
Anyone want to buy a self venting can cheap?
