Motorex 645 for Exhaust System?

[COBlue]

'05+ Owner's manual recommends 645 for cleaning and protecting the exhaust.
Didn't find anything in a thread search.
Any sources or acceptable substitutes here in the U.S.?

Not sure about the suitability for the exhaust, but I likes the ACF 50 Aircraft spec for keeping rust/tarnish at bay on the rest of the metal work..............

Check Cycle Gear they carry the Motorex line of products.
