Paul,
I used "FlameSafe" FS1900 Sealant, which is Intumescent and
elastomeric and several other big words but claims to be a 'Firestop'.
I stuck it on SS plate, on GraSing's firewall material and by itself and
stuck the blowtorch blue on it for 15 minutes. It didn't like it and turned
black then orange and glowed but didn't budge (well maybe one or two
particles departed). I took photos of the display for my inspector.
The stuff comes in a 10oz cartridge so needs a squeeze gun and
it's pretty rubbery anbd resistant to move, but it does jam nicely into
crevices samller that the hole you cut. It can be finished with a wet
spatula for looks and will harden in hours - overnight is good. For
inspectors and their ilk, I then finish it off with fireseal which is good
for 250deg and shines nicely. They know. You mustn't eat it, lick it or put
it in any waterway and it can cause cancer, and birth defects. It's too late
to avoid the latter anyway..
