My understanding of WD40 was that it was wax and oil, neither of which, I assumed, would evaporate. I know it sucks as a lubricant, but I thought it would do what it was designed for - prevent rust - well.

I'm not trying to hijack my own thread - I know WD40 is discussed thousands of times on these forums - but it seems like a perfect solution, and it leaves the bike all shiney!

And, yea, I ride with fenders when it's looking like rain.

Thx for the reassuring words. I didn't think it was that big a deal, as long as I took some basic precautions.
