When I first got on here, Molekule (sp??) was the main science guy. He was the one you'd get into real technical discussions with like the affinity of carbon, oxidation, organics, etc.etc. and Bob was the "hands" on guy. I found this site looking for an alternative to Mercruisers High Performance gear oil because that stuff, even then, was really expensive. Bob's point was that his oil could better handle water intrusion than Mercruisers, so I suggested we do some sort of "test." Well, leave it to Bob, he got some containers, put Mercruisers oil in one and his in the other, added water, and shook it to get it all mixed throughly. Well, he proved his point to me. Very intelligent guy and I for one, have missed him since.
