Been using s100 for a good 15 to 20 years works great!

 

I've used them ALL!&nbsp\\;&nbsp\\; Spray on Pig Spit and wipe off the really dirty areas.&nbsp\\; Go over the same areas again once or twice extra.&nbsp\\; It layers on.&nbsp\\; Don't overapply or you WILL get a sheen!&nbsp\\;&nbsp\\; Remember to wipe off the chrome after each application.&nbsp\\; I usually retreat after three months or so depending on dust and rain exposure.
