Re: Fleetwin Exhaust Plate

[Bob Wight]

I concur with the recommendation to NOT use any gasket compound or anti-sieze product that contains copper due to it’s adverse reaction with aluminum in the presence of water or moisture. I have seen the Permatex Indian Head Shellac used but I prefer either BRP Gasket Seal Compound or Permatex Aviation Gasket Sealer #3 for sealing gaskets. I also use the same gasket seal compounds on cylinder head bolts, exhaust cover bolts or screws, lower unit attachment bolts and water pump fasteners to act as a thread sealer in lieu of using anti-sieze compounds. Some anti-sieze compounds also include graphite, copper or other dissimilar metals that will react with aluminum. I’m not intending to start another anti-sieze debate here – just my thoughts.
