This was my first time using One Shot, recommended to me by professionals. A friend and I needed to paint carousel horse saddles at a free soupy kitchen / playground in NJ. Most of the horses had not been painted in 80 years and kids were sitting on the horses with wet bathing suits. We scraped, sanded and primed the saddles before using One Shot. We were concerned that the white primer would streak through the brown paint, but the One Shot covered beautifully with one coat, and a quart can did 41 saddles with some left to spare for touch ups. Hopefully this carousel will raise funds for a further restoration, but for now the saddles are protected.
