You had an ex that kept giant tubs of Vaseline in the house and you let her get away?
I'm pretty sure that the "OR" series of gloves are exactly the same as the "RBG" series, just pre-dating them a bit before Rawlings changed their numbering system. Even the earlier RBG gloves have pretty nice leather, much nicer than the newer ones.
I have used Vaseline and never noticed any ill-effects. In fact, some gloves turn out pretty darn nice from it. The only reason I don't use it more is that I like the results from Lexol or straight lanolin just a little bit better.
Does anyone remember the flap (covered in the Glove Collector newsletter) over Vaseline use when Noah Liberman published his "Glove Affairs" book a few years ago? The chapter on glove care was dead set against using petroleum jelly. Liberman's argument against it was based partly on his statement that petroleum jelly "...isn't an oil. Technically, it is a wax".
He went on to say that petroleum jelly doesn't penetrate the leather and attracts dust and dirt. My own observations are the exact opposite of that.
The book recommends lanolin as the absolute best leather treatment. The funny thing is, if you do some research on lanolin the technical data says that lanolin is classified as...a wax!
