Keep in mind that if it is a CrMo frame, the steel is somewhat resistant to rust anyway, unlike those with much lower or no Cr in the metallurgy.
This is the one thing WD40 is useful for. I use it to coat my bike and gun parts.
Protip: Buy a gallon jug of WD40 and a $2 spray bottle from WalMart. This is waaaaaaaay cheaper than buying the pressurized spray cans.
