Cheers Nog, seems cheap enough.
Are there any places you must not apply it apart from brake pads/tyres? And do people's experiences bear out that one treatment will last a long time, doesn't wash off in first downpour etc? And (questions, questions!  :rolleyes ) how many applications will one can do?
I've used WD40 to help protect certain parts of my previous bikes, but it's not ideal.
