This product worked miracles. I used it in tandem with Rejex finishing polish. The plane was rained on during the Canadian fires and left a nasty gray coat on the surfaces. I cleaned it originally with another polish and I thought it looked good but after using this product it was considerably noticeable how much more smoke and ash came off. I used it with a buffer pad and holy cow it looked fantastic. I am keeping this product at my hangar from now on. It even removed other imperfections I thought were permanent.
