The chrome bumper on my 70 F350 has some surface rust and it is getting worse.

#1: what is the easiest and best way to clean it up?

#2: once cleaned up what is the best way to preserve it?

#3: or.... what would I need to do to the bumper if I choose to paint it?

#4: what color were the non-chrome bumpers painted?

Thanks!
