Long story short - I've started using this on my commuter and road bikes. Aplication is ridiculiously easy and if it lives up to half the claims for film strength - I'll be happy. Apparently this was originally developed for chains that had to contend with salt water exposure -ie oil rig equipment. I drive in the winter on salted roads so will keep you posted.
Anyone else already tried this?
