Tri-Flow, IMO is way too light. Also I'm thinking you may not have been saturating the rollers enough, and as already been said, any water in the chain wasn't being displaced. On the new chain I'd go with Pro-Link or ChainL. After a ride and the chain dries, maybe u use a stiff brush to get the grime and grit off before applying the lube. Put lots on the chain, spin it around a lot, and wipe the excess of. I wouldn't use Naptha except occasionally on a rag to wipe the heavy grime off. I think the proponents of minimal washing and leaving the factory grease in the chain, just supplementing it with the lube, is your best bet.
