I found my sealant. Its by NAPA and called Aviation Form-A-Gasket part#765-1210

It says max 400 degrees though so it would not be good for exhaust applications but has served me very well over the years in non exhaust applications.
Thin with denatured alcohol so that can probably be used for clean up too.

Edit:
I just tried cleaning up the can with Isopropyl and it came off with a little scrubbing.
This stuff may not be Glo Fuel resistant
