The inflation/sealer on the left dates from the 70’s or 80’s ? The one on the right is the new version purchased from the big box store today.
The instructions read pretty much the same for both — never had to occasion to use the older one, and I imagine the propellant is long gone. Still sloshes the fluid inside.
Apparently the stuff will seal and inflate the tube to a degree but not to the point of over inflation?
Both cans says to inflate to recommended pressure after emptying entire contents and spinning the wheel to distribute the sealant.
Might be easier than a disassembly road repair — assuming it actually works. Here is hoping I don’t find out! 😉
