WD40 and GT85 are both pants as a lube... The Monty Chain Spray is similar to the Finish Line Dry Wax someone mentioned above, works great, certainly better than *insert random household oil*. The idea, as Hudson said, is that you spray it on wet, the solvent evaporates and this leaves a dry waxy coating on your chain which doesn't attract dust and crap. Pretty sure it says exactly that on the site actually... haha, sorry for repeating myself. Ads
