I have used naval jelly to get rid of main rust, but I cant get the rust out of the pitted areas. Any ideas on what to use??????? THANX

Try Oxy-solve, keep it damp.
Otherwise, metal etch, the type you use before you paint a car.

Rustmort does a good job of getting in pits & cracks!

Try "the works" toilet bowl cleaner. Has hydrochloric acid in it.
