Had this very nice ( Stiffle) very heavy polished brass lamp that screamed 1980's (mainly because that's when we bought it). Now tarnished and looking a bit shabby. Wife mentioned giving it to Goodwill and buying a new lamp - all I saw was $$$.
Spent an hour or so disassembling and wet sanding, a couple of light coats of primer followed by several light coats of Rustoleum Rubbed Bronze rattle can and a new shade and voila, a refurbed lamp the wife loves all for a couple hours of labor and $10 worth of paint:
