Hello John,
Well, we just received our second batch of FKM sealant to test for use on the Supra gaskets. This is the material that will enable us to “rubber stamp” our gaskets as streetable. Right now the sealant we are currently using “silicone” is not resistant to the chemicals in today’s oils and coolants, which is really limiting us to high horsepower engines that require a freshen up ever 1 or 2 years. The only other material out there that is resistant is Viton and that test went bad, really bad, like ruined tooling kind of bad. So hopefully on this test, the chemists have sent us the right mix and we can actually get a chance to apply it to a test gasket and see how it first of all works with the tooling, bonds with the copper and holds its shape. So, until all of this testing is done and we put a gasket in a motor and see how it runs, it might still be a few weeks before we say that this is a go or a no-go.
Thanks for your help and patience,
