Parts Stop stocks WD-40 Multi-Use Product — the original blue-and-yellow can, in a range of sizes from the small can that lives in the ute to the big one for the workshop bench. On the shelf, ready to go.
WD-40 came out of a small San Diego lab in 1953, where three blokes at the Rocket Chemical Company were chasing a formula to stop the Atlas missile's skin corroding. It took forty goes to get right, which is where the name comes from — Water Displacement, 40th formula — and that same formula is still in the can today. Worth knowing what it actually is, because it's the most misunderstood can in the shed: WD-40 is a water-displacing penetrant, not a grease. It shifts moisture out of a wet ignition or connector, creeps into a seized nut, frees a stuck hinge, cleans off gunk and leaves a light film that holds off rust. What it isn't is a long-term lubricant for a chain, a bearing or anything under load — for that you want a proper grease or chain lube, and we've got those too. Grab the size that suits.
