Best stop leak for a very minor head gasket leak

[Smcatub]

So has the K-Seal done anything yet? I know it's only been two days, but I'm curious whenever I see somebody trying out a 'mechanic in a can' type product. I've never really believed in them, but Lucas fixed up a slipping transmission for 10k+ miles on my Ford Escort (Got rid of it not long after, so who knows how long it lasted) and Sea Foam quieted down a Volvo engine that sounded like a machine gun, so my opinion is starting to change on the matter...
