Bill-
So it looks like the Aviation sealer is basically the same as #2. When would you use one over the other? Is the Aviation sealer basically "better" (and probably more expensive) #2?
I also gather that the "High Tack" would then be your general all-purpose gasket sealer that is used everywhere except for non critical places that have a high chance of being dissassembled in the future (valve cover, oil pan, pushrod cover).
Does that sound about right?
If it basically boils down to two products then I think I can live with that.
