In case you guys were wondering about applying Obenauf's LP to 1Ks in Rust, I just went through with it today - along with oiling some other boots and an old leather jacket. They came today from Nordstrom and I wanted to get them conditioned, as winter is rolling into Boston. After the discussion several pages back, I went with the 9.5 (I'm usually a 10 in most casual shoes) and discovered that they weren't as loose as I remember when trying them on at the Tannery. I just had to manhandle the laces a bit when tightening. These boots are some kind of crazy magic; at once both supple and sturdy. Comfortable out of the box. Not like those stiff, bulbous Red Wings. But I digress.
To condition them, I pretty much followed Crane's method for applying Sno-Seal. I microwaved the LP for about 30 seconds and applied a liberal coat with my fingers to the uppers and outsoles, brushing the stuff well into the welt with a horsehair dauber. Then went over it with a hair dryer on high with medium-high heat. I let it dry for about 25 minutes then buffed firmly with a cloth made from an old tee shirt (gets off the excess LP and smooths out the coat). Then I did the whole thing again the same way. Finally I grabbed a horsehair brush and brushed each boot until each of my arms were tired from brushing each boot (I was a few drinks in at this point, and rather obsessed. Don't remember how long that took).
Surprise surprise, the LP didn't really darken the boots. But they drank the stuff in, so I'm confident that they're protected.
