(PLEASE READ THE EDITED PART) Hello "Oldster"
I have another suggestion for you to try: If you have a piece of brass or a copper penny you can eliminate the rust spots by using the edge as a scraper and CLP to remove the spots with minimal damage to the finish. After you have thoroughly cleaned the areas you should try "Prelim", I think it's called (Made and sold with Renascence Wax) please do not use excessive pressure as this product must contain "Pumas" and will remove bluing if you are over zealous. After this application and the wipe to remove all the residue use the "Ren Wax" application and watch the bright blue emerge as you proceed. Both products can be purchased from many sources and seems expensive but the products do go a long way and are worth what they cost, IN MY OPINION! Let Us Know If YOU Try This Suggestion and good luck with the RUST removal!
Charlie Sides just informed me that the PENNY needs to be 1982 or earlier, the post 1982 Pennies contain ZINC and will damage the bluing, hope this is in time to prevent any damage, sorry! Didn't realize we could cheapen the value of a penny!
The "pumas" was intended to be "pumice", my appologies.
