Well today I tried something different. One side of my face was prepped as usual and the other side had the addition of of a "Skin Milk" cream applied on top of the lather and worked in.
Man, did that make a difference! The "Skin Milk" side shaved much easier and closer!
Perhaps the preshave oil thing has something going for it?
Of course, I bought the stuff at a garage sale, but so what, it works!
