Great Product

This WD-40 corrosion inhibitor product is another great product from the company. It lubricates well and it "sticks" to surfaces and stays on the surface very well. I see this preventing corrosion by how it adheres to surfaces. It worked well keeping my garage door track lubricated. I also used it on 12 volt electrical system parts and am pleased with how it help keeps the electrical connection making contact especially with trailer plugs. I also like the product pressure as it comes out of the can as it assists in penetrating into small and deep areas.

Easy Application

I got this for my sliding glass doors as well as my two garage doors. Both were becoming increasingly harder to manually open. One spray of this and they all open and close smoothly now. I'm confident I won't have to re-apply for quite some time as well.

Same trusted brand same quality product

This works great just like the regular stuff but is suposed to inhibit rust buildup. So far ive used it on door hinges rusty bike brake cables and shift cables. It definitely does the job. Same trusted name brand but better.

Reliable!

Can never go wrong with WD40 products. I used this item to protect some motorcycles parts. I found it to be a good steady spray and spreads evenly. It’s only been a few days but I definitely think this will hold up over time.

Great at loosening rusty items

While I can not attest to the corrosion inhibitor aspect of this product (I have had it for a week) it does work wonders on rusty nuts. I had to remove four of them and ran out of WD-40. Works just the same. After spraying the nuts and letting it set for half an hour, the nuts started to budge and come off. Definitely as good as the original.

Great

I bought this about a month ago and it's during the winter months so I have a lot of wear and tear on my snowblower and I was worried about corrosion so I tried this and it seems to be working great it doesn't wipe off just by normal use you would have to go in and give it a good rub it seems to be working on my lawn mower as well I don't see any corrosion or anything.

Absolutely a must have if you live in the south!!

I've been using this primarily on tools to help prevent surface rust from the high humidity where I live. So far it's been working amazingly and its just so simple! Anything from wrenches, screwdrivers, sawblades, you name it and this product will protect it! I almost wish they sold a gallon size with a built in sprayer. Overall, it's now a must have in my toolbox and I highly recommend!!

Works great, replacement for grease

This rust inhibitor works great for indoor as well as outdoor equipment. I have aplied for all hinges on doors in the house and also applied for garage door too. High pressure nozzle works great to reach the area which regular grease do not flow. Its been more than 5 rainy days and i haven't seen any issue with rusting or squeaky sound. So it worked best for all my applications.

Best ever

I received this item so happy I did. Came very well packaged. WD-40 specialist long term corrosion inhibitor has been the most helpful stuff ever. Where I live everything rust in the winter time because of the salt. Since using I've had no issues with rust. I used it on my trucks , snow blower , tools. I love it . I recommend this item you won't be disappointed.

Looks nice so far

I got this mainly to use as a rust inhibitor for my knife/blade collection. I've got several antique tools/weapons that I keep in storage that I don't want to futz with as far as cleaning and continuous maintenance. Can't speak to it's long term effects, but goes on well and makes the metal look very protected. I've trusted this brand my whole life, so can't imagine it'll be a problem.
