For lubricating your cams, we recommend Metolius Cam Lube because it is self-cleaning and waterproof after it has dried completely. When dirt attaches itself to the fully dried film, small particles of the lube will break away, carrying dirt with it. MCL keeps cams working smoothly and helps them last longer. Graphite lubricants like Lock-Ease and oil-based lubes like WD40 or Tri-Flow also work, however oil-based lubricants attract and hold dirt particles so they aren't recommended for dry, dusty environments.
