WD-40 Specialist Long-Term Corrosion Inhibitor, 6.5 OZ [6-Pack]

I’ve used this for a couple years on my 2013 pickup truck and it seems to have slowed the rust of frame and even body components. It forms a hard black surface at rusting areas. I’d recommend wearing a mask and safety glasses when applying.

Worked great on AC coils etc. Seems to have stopped corrosion in salty environment. Going to put cleaning and WD 40 corrosion inhibitor application on a 6 mo schedule.

Haven't used yet, but expected standard size. These were a bit smaller. I'm sure it'll work great. Never a complaint with WD40.

I’ve tried all kinds of protectants and have for this product to be the best on my long-term tool and gun storage needs. If I need a tool, I just wipe down the handle and go to work. The tools I didn’t treat showed rust within days/weeks, the treated tools have not shown rust after months. I live in the South and high humidity is a year round problem.

I purchased a 6 pack of these for 70 bucks and expected to use 3, 5 cans for my car's undercarriage but no. The cans are tiny. The contents are under high pressure so it goes quick. You will use up the can in probably less than 50 seconds of spraying. The product does goes on thick and creeps. It is reviewed better or as good as fluid film but for the price and size, it is an expensive disappointment. Just go get the Fluid Film. Costs about half as much. Both products are lanolin based and there's not need for WD-40 Corosion Inhibitor to cost this much in comparison.
