What does everyone use? I hate the sticky stuff that collects dirt and dust. My favorite is Dupont Chain Saver wax based lube with Teflon. Non stick, quiet and stays on for a good while. Chain stays looking new on road bike. MTB, just hose off mud then spray it on. Cans don't stop working until contents are gone either. That's why I never use Repel insect repellant as those are notorious for that problem. Go Cutter for best value and function.
