I am changing my skins to Stainless.  Does anyone know where I can get the type gasket material Greenwood uses?  I used high temp silicone originally but it is a pain to remove.  Greenwood's gasket looks much easier to work with.  I checked local plumbing/heating wholesalers and automotive stores with no luck.  I also called a few Greenwood dealers but was unable to reach a real person...  Thanks!
