That's what I think. He's speaking about the goo in pressurized cans. If he is where I was just a few months ago, he isn't even aware of the traditional shaving products.
When I started using the shaving soaps and creams I have to order online because I can't find them anywhere in town, my skin began to feel that solid, robust sensation the author describes. I cut myself on occasions that I "zigged" when I should have "zagged" with my razor. The use of a brush probably contributes to the therapeutic effect.
There has to be a reason I like shaving after I hated it for 40 years. The author found one piece of the puzzle, the goo, but I think I've put the puzzle completely together. Maybe we can contact this person and invite him over here.
