I have quite a few old and damaged cans of foam, some are years out of date and dont flow into the guns, some have the tops damaged.
If I pierce one with a nail then i could maybe use some of the foam which would erupt out, but is there a better way of doing it, maybe garffertaping a funnel and hose onto them ?
I also have several old cans of foam cleaner, with not enough pressure to clean out guns or spray, but with liquid/gas still in the cans. How can I collect or use this ?
I will try to get the experiments videoed for your entertainment !
