Note: If you choose to use a "dip" product such as that suggested, you need to "Neutralize" the acid after dipping the $200 - by running it under cold water for about 10 secs - and then immersing it in a solvent such as Acetone for about 10 seconds. If not, the Strike will begin to re-tone at a much faster rate than before the treatment.
Also, never use on $10 Strikes as the rims are made of Brass.
