I go with (b) too and swear by ACF50 and a spray of FS365 after a wet ride. I've even run in a couple of Harleys over winter having applied ACF50 the day I got them, and sold them in showroom condition.

The thing is, the ACF50 option can be a bit stressful as you watch your bike get more and more grimy and salty and wonder "Did I miss a section, or a few fasteners?"

I currently have a brand-new R1200GS that is covered in ACF50 and totally plastered in road grime. It's taking a lot of will-power to not give it a damn good clean and polish!!!

I tend to give the bikes an occasional hose down with cold water just to get the worst of the crap off as I don't want to scratch the bike with all the grit on it, and then come January I'll do a full clean and re-application of ACF50.

It's stressful, but a damn sight better than hibernating the bikes for 5 months!
