Since I wanted to try out the two OFMP greens, Lexington and Tavern, layering seemed the best way to go. The first layer was Lexington. I added Extra Bond after a bit of research, since stain came off onto my sponge when I was cleaning in preparation for painting and I didn’t want to use shellac. The supposition is that the Extra Bond would seal in the stain if I mixed it into my first layer of OFMP. It covered well with not a hint on the dark stain bleeding through. So far so good.
