I agree with this 110%. Stuff happens. Even the most experienced person has stuff happen. Freeman also just spoke the "golden rule of finishing"...aways work it out on scrap of the same material. Never on the actual project. One the back, instead of trying to stain/dye it black, have you considered making it solid black? A black "stain" is incredibly difficult to pull off in an even way. Going solid answers the mail with great contrast for a nicely colored body top.
