Lesson learned slow. Do not buy Great Stuff foam in
advance. Goes bad, and throw it out when it doesn't
work.

Just put about five cans int he trash.

Also, great stuff foamed into air spaces around the
vehicle, slows down rust. Fenders, under doors, etc.

The foam is impossible to get off clothes or skin
when wet. Treat it like toxic waste.

Carry empty shopping bags. When the can is exhausted,
stuff it tube first into the bag.

I'm heading for the store, to buy another can of foam.



I agree with everything except for your first comment. I've used unopened
cans of Great Stuff at least a year after they were bought with no
problems. Perhaps we need to know your definition of "in advance".

I don't know about the rust prevention, so I'll take your word for it.

2 other tips:

1 - You'll need less than you think to fill a gap, it will expand beyond
the opening. Expect it, embrace it.
2 - Don't put your window or door trim back on for at least 24 hours. When
#1 happens, it'll ooze out from behind the trim and be a real pain to clean
up. BTDT
