I know my “test” of anaerobic sealant on a Mercury tank is not very conclusive because it was more a vibration test than a time endurance test. As I said, it was an experiment…..but it was based on the fact that manufactures have been using this sealant on crank case halves for many years, now, to replace the old “Type M,” 847-type sealer, that was failing due to ethanol. That sealer used to work GREAT, before ethanol came along, it would seem; but not anymore. Also, I don’t know what they mean, exactly, by “solvent-based sealant?” If there truly IS something that stands up to ethanol based fuel, even better than the anaerobic type, I would sure LOVE to know what it is! The article doesn’t name an actual brand.
Note: I tried “Yamabond” one time, in direct contact with gasoline and it turned promptly to mush.
Long live American manufacturing!
