I have ACF'd my last 3 bikes and they have stayed mint as a result. I don't care what the naysayers have to bleat about, the stuff works. Clingfilm over the brakes and disks then newspaper taped around them. Tyres covered with an old sheet. Best to use a spray mist from a spray gun but I just use the pump bottle and buy the stuff in bulk. Wash, clean and dry the bike, mask up and then liberally spray every nook and cranny. Pay special attention to the underside of cylinders and engine casings and I remove the sump bash plate for this. Once coated, I leave for 10 to 20 minutes then wipe all the excess off from wherever I can (I don;t leave it to gather dust and crud like some do), start the engine and wait for the stuff to burn off hot casings and exhaust. Job done. I do mine like this every 6 months and then after every few weeks riding I go over the frame, engine casings and wheel spokes/rims wiping down with a rag. 1 large bottle of ACF last me several years.
