WD-40 Specialist Corrosion Inhibitor, Long-Lasting Anti-Rust Spray, 6.5 OZ

2nd purchase and great product, A little expensive for this small can

I use this on highly exposed parts on my RV. I primarily use this for prevention in areas prone to rust. The best prevention is to ensure any rust is removed and painted appropriately. That being said, there are simply places that cannot be painted, such as scissor stabilizers or areas exposed to road debris. This is where this product comes into play for me. In one situation, simply because I did not have the time to properly fix it, I just sprayed it on the affected area to prevent further rust. By the time I got back to it, the rust was almost entirely removed. Because it was more of an unsightly issue than a critical component, I let it sit longer. After two weeks, it just about removed all the visible rust and protected the part even in dusty and arid conditions. It didn't seem like it dried out. I was impressed. This will be used for removal, prevention, and quick fix to prevent further damage until it can be properly fixed. Overall, this is a good product, but a bit pricey. Time will tell how much a 6.5 ounce can will last, which will ultimately determine its overall value. For effectiveness, it works great. I would recommend.

I put this stuff on all my rusted parts

I have a woodworking shop near Houston. It's very humid most of the year and fighting rust on my cast iron tools is a constant battle. I tried this WD-40 corrosion inhibitor and had mixed feelings about it. First, it's a really small can for the price. Second, it works really well, but leaves a sticky coating. Unfortunately, wood cannot slide smoothly across this coating. The sequence I have developed is to spray a thin coat of WD-40, rub it on and cover the tool. When I need to use the tool, I uncover it, wipe off the WD-40 with mineral spirits and apply a coat of wax. When finished, I recoat the tool with the WD-40. It does stop rust, but it's not practical for my use.

This stuff works great on sun damaged outdoor furniture!

Great product! For rusty hand tools, I take several steps: 1. Place all hand tools in a 2 gallon bucket of distilled white vinegar. 2. Let stay for 3 to 4 days. 3. Rinse off with hot soapy water, and use dish scouring pad as necessary. 4. Dry with hand towel. 5. Spray joints with WD40 lubricant, such as pliers and wire cutters. 6. Spray this rust inhibitor onto each tool while holding tool in a 5 gallon bucket to catch the overspray. 7. Wipe off vinyl or composite or wood (hammers) handles with a soapy rag. Tools are now as new and protected from rust. This rust inhibitor works much better than WD40 penetrant for rust protection. Think of WD40 penetrant and this rust inhibitor as being complementary, not just one or the other.

Great protectant.

Excellent product as always. Spread it on some rusty areas. We’ll see what happens. Come the end of winter.

Nous avons 2 voitures pas recentes mais propres, j’ai testé cette enduit sur quelques pièces et surfaces avec de la corrosion puis verifié le resultat apres avoir passé un hiver Canadien. Je suis surpris du résultat, le produit dilue la rouille puis sèche apres environs une journée laissant une protection qui a passé l’hivers. Oui c’est Très dispendieux pour une petite bouteille mais je le recommande tout de même fortement.

Great for long storage of machinery with cast iron surfaces etc

Very useful , meets the expectations.

Como ingeniero metalúrgico sé que ninguna pieza metálica se salva de la oxidación, incluso si están almacenados (claro, a menos que estén al vacío). Hago trabajos eléctricos y de fontanería por pasatiempo, por eso sé que invertir en buenas herramientas es ideal para evitar hacer gastos recurrentes en nueva herramienta, después de cada trabajo limpio toda la herramienta que usé (elimino polvo, remuevo óxido superficial con cepillo de latón) y aplico este lubricante, es el que elijo por los resultados que me ha dado, no sólo protección contra la oxidación y corrosión en herramientas, también en bisagras, cadenas, soportes metálicos y otras aplicaciones. Las herramientas que ves las he tenido por más de un año, algunas son de años, pero teniendo el cuidado y mantenimiento adecuado pueden parecer de ayer. Nota: Una vez que rocías el lubricante en el objeto deja una capa "blanca espesa", esta desaparece en varios meses si fue abundante, si fue una capa fina y la esparces por la superficie no es notoria.

Bottle is quite small and delivery took a lot more than it stated on order details
