I'm not sure what automotive finish you have in mind that would be cheaper and easier to apply than NC lacquer. Also, automotive finishes are generally more brittle and less accommodating of expansion and contraction of wood. An automotive finish may look good now, but in a short time it might begin to check and crack. I'd stick to products designed for wood. Why would you want a poly-like high gloss look? Its a ton of work to get it smooth enough not to show defects, and it generally just looks cheap. Go for an ebony satin using lacquer. Steinway does.
