Harvey,

Thanks for the tip. But I was planning on engraving about 150 key rings to have on hand and sale as "impulse" items when people saw them. If I needed to do one or two or three trophy plates -- or something similar -- it might be worth the extra effort to polish, wax, etc. But in this case if they can't be done "quick and dirty" it really isn't worth it. At least, not to me.
