This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.
First I removed hose from drain, next I loosened the clamp at the drain hose connection at the washer. Removed hose. Have rags/towels as there is some residual water that will spill out of the washer. Reinstall in reverse.
