It sounds as if you've decided to go ahead and use it, and that seems the best course to me from everything you and others have said. I did have a Canon 50 f/1.2 screw mount lens serviced by Focal Point. Apparently, VanStelten used a GREASE with a high viscosity. It migrated over a period of 9 months, and a total of TWO rolls of film using that lens, no extreme temperatures either in use or storage. Because it wasn't oil, the grease caused the blades to bind and rendered the lens unuseable. Even under examination, because of the use of grease and not oil, there was no shiny telltale sign. Your case is totally different, but mine is an example of improper repair technique, and probably improper volume of lubricant. Have a grand vacation out West.
