imho:
I was told for polyurethane expanding foam, and this was re-affirmed
after reading fire blocking foam can, that you leave the straw alone
filled with foam. When you want to use the can again, you snip off an
inch of the straw and then start again. It seems the tip will harden
and protect the rest of the straws contents. Check the the can out,
it might have a different set of instructions.
