Hi All,
I'm after some advice,
What is the best way to apply ACF50 and where can you put it?

I got given a brand new can for my bday on tuesday so after cleaning the bike i put a small ammount on it, front forks exhaust, swingarm and frame. Evened out with a dry cloth to give a good finish.
I was thinking of the plastics too but that doesnt corrode so Tesco's Dashboard shine went on them as i was out of protect'n'shine or autoglym bike polish.
So, what's your opinion?
Put a good ammount and buff on or just a little?
Also, if doing the engine, how?
