My canoe building instructor showed me a different, easier way.
Apply first coat, hand rub, apply second coat. Attach canvas to car buffer and let the buffer do the work. If you do a third coat, repeat.
As far as how you make the mits, the buffer method cuts down on the number of mits you have to make. And the results were far better then when I hand mitted the whole thing... and ... I saved a ton on elbow grease.
