I have dug out my old glove and need to figure out what kind of oil to use. I haven't used the glove for about 8 years, it isn't too flattened out or stiff, but it does need some shaping. The glove is a Rawlings and is certainly more than 30 years old.I see all sorts of oil brands in the sports stores. We used to use Rawlings Glovolium but I haven't found that in local stores. Do you have an oil recommendation? I prefer a non heat method.Thanks in advance!
