Basic rules apply. You don't need to be polishing all weekend!!!
I have a mate on here who has a 2006 GSA, never polishes it but does clean and ACF50 it regularly, at nearly 40k mls there is NOT ONE spot of corrosion on it, at all.
A lot of people blast their bikes with a jetwash, not a good idea, especially if there is salt/dirt all over it, all that does is blows the salt into places it cant get out of, so the rot sets in....
I would remove the front engine cover to expose the belt (4 Tx screws) cover the engine casing in ACF50, as well as the front of the cylinder barrels and heads......
As an interesting point, I bought an ex police 1200RT with 50k mls on it. They NEVER clean their bikes properly, I removed all the fairings when i got it and used a good de-greaser then hosed it off, like new underneath! 4 years of road grime and dirt had protected the paint etc!
