Try a little DOT 3 brake fluid if you have some

On another note, you have to be careful using this stuff to insulate
around a window, too much and you might not be able to close the
window. My father mentioned that there was a similar product that came
in the same form except that it didn't expand, I forget what it is.

I only use insulation scraps around the windows.


yer right about the expansion, i had to remove it and re-do it.
