For insulation (cushining) around the mic I have used the insulation
that can be purchased for water pipes at the hardware store. It comes
as a black foam rubber type material in a long black tube with a slit
down the side. Just cut the length you need, a mic fits in nicely being
the same diameter as a home basement water pipe.

I would not trust the solvents not to hurt the mic.
You don't have to hold it that tight, it's probably not a good idea to
glue the mic. I've always used small bits of foam. Packed in place they
won't move, but you can take them out anytime. The one I did in the
photo was the done with thin strips cut from the pink foam sheet used to
wrap computer things. It won't soak up water if it came to that. I just
wrapped the strip around the mic, and shoved it in place. Takes a little
adjustment of the amount of foam, so start with excess and keep trimming
off until it goes in moderately tight and it will hold fine. My original
the mic was held that way and gave no problems in two years of heavy
use.
If the mic came with a tiny foam windscreen, mount the mic so you can
slip the foam on. It won't do a huge amount of stopping the wind, but
helps a little.
