Its yours .Do as you please . Don't Get me wrong ,I like rust(patina) just as much as the next guy. Most my pumps I have not touched. But if the only way I can get a few in the house is restored , then so be-it. A lot of the major brands back in the days had pretty common paint schemes. Some pretty boring .Just one color and do beleive they need just a little more than that.
