Bernie, welcome back ashore buddy.. 😆
Randy, I’ve just re-re-read what I wrote, I think I must have been in vague mode as I’d been inhaling some oil/varnish fumes .. 😳
What I actually should have made clearer, in regards to Dons study, was that he was talking about surface tension in relation to the oil.
His comment was that when watch parts are cleaned in a traditional manner, a micro film of cleaning solution remains, this film will prevent the oil drop from spreading but it also contaminates the oil.With USC cleaning, there is no film residue left, so surface tension is zero and the drop of oil spreads across the surface and away from the parts it needs to lube.
He speaks of this issue and the way the Swiss combated it, by applying a coating of stearin acid to the USC’nd parts, he also mentions Epilame treatment which is a fatty acid solution that was applied by brush or vapor in order to keep the oil contained in its droplet form..
Ok, that’s waay too much info for this time of morn with only one coffee

What I meant was what made it shiny after the USC, not the USC cleaner. You know, the side you made shiny after the USC? Can you offer a comparable product name that would get results like that?
To be honest, I really don’t know much about chemicals. I suppose it’s something I should read up on to get a base. Are you basically saying the shiny side was done with some straight ammonia?
Thanks Chris!
Best,
Tim
