Keep the mechanical components in your motorhome moving freely with the new 3-In-One Lock Dry Lube from the WD-40 Company. The PTFE-based clear formula dries within minutes, and wonâ€™t attract dirt like other lubricants can, according to the company. The attachable straw delivers the lubricant into narrow mechanisms, allowing it to penetrate quickly and deeply. 3-In-One Lock Dry Lube is safe for use on metal, wood and most plastics, and the 2.5-ounce size easily fits in small spaces like toolboxes and glove compartments so itâ€™s always handy. MSRP: About $4.
