Is the OMC sealer ethanol proof?
Thanks, Bucc

I can’t answer that question, but the Yamabond 4 / Three-Bond and Permatex Ultra Grey products don’t seem to care one bit about any solvents, oils or fuels, so far as I’ve ever known.

And FYI, I use yellow Teflon plumber’s tape to seal fussy copper & brass flare nut connections. At first, I add a couple turns to the threads.. and if that doesn’t seal it (it does, 90% of the time) then I add a single layer to the seating surface itself. Never had it fail, but as ever, YMMV.
