Small cans of expanding foam?

[Downeaster]

Does anyone sell a smaller can of expanding foam?

No matter what I've tried, "saving" a partially used can never works. Foam dries up somewhere in the valve or wherever and the remainder of the can is useless.

Smallest I've seen (and the ones I usually buy and waste most of...) are 12oz.

Even a 6oz can would help.

Have you tried Great Stuff. The end of the straw is sacrificial. Can be used a few different times until the remaining straw becomes too short. See vid.
