3M 'Scotch-Seal' 800 Industrial Sealant, Rex!
I believe it has an -80 OEM number.
(But I 'spose I should have searched it to see if it is still produced; I'm down to two tubes.)

PS: I had Yamabond4 fail for me. But it was an OHV with a leaky petcock.Last edited by T. Cotten; 05-01-2022, 04:07 PM.AMCA #776

Seems like I bought a tube of hylomar at NAPA for the Buell several years ago, but it isn't listed now.Last edited by Rex; 05-01-2022, 06:57 PM.
