Black expanding foam sealer

[Chateau_Nomad]

Due to some of my modifications I've had to dig out several places where plumbing and propane hoses come through the floor. So I have gaps that need re-sealed against critters, etc.

I know that the yellowish expanding foam is available at big box stores, but I'd rather use the black/gray colored stuff like Thor uses. Is there something special about the black foam? And... where can I get it?

Thor sure has that stuff in Gray, cause there are turd piles of it everywhere under my rig where they seal up passthrough holes.

Yup! I've been digging out those piles with a screwdriver!
