Protects for a long time

I have to say I was quite impressed with the longevity of this corrosion inhibitor after treating my trailers, boat and zero turn mower. It does a fantastic job of blocking rust and corrosion, especially in wet, damp conditions. The ideal solution to keep my equipment in tip top condition while stored in the off season.

Appears to be working great

So let me tell you this stuff almost appears and comes out the can just like fuild film. So far its working I have it sprayed on my pickup trucks two batterys terminals. also sprayed on the hinges of my truck all the way around. Hopefully last for a very long time

The best I’ve used

This stuff works great. I didn’t think I would get much use out of this product. I assumed it would be a one time use type of product. I was truly wrong, I find myself using this product more times than I care to admit. From my fishing rods to my car. I am a very satisfied consumer. It’s thicker than the regular formula. This truly the best product I used for rust prevention. I swear I use this stuff on things that have rusted and things that has the potential to rust. No complaints at all except for I wish it came in a bigger can.

Works Great

The WD-40 brand is something that is always in our household. This specific one is the one I use outdoors mostly. I have sprayed it on hinges on my shed and the hinges on my car doors. The corrosion inhibitor is helpful as it is long lasting. The idea of keeping away corrosion while taking away squeaks is wonderful.

Used on Car

I used the WD-40 Specialist Long-Term Corrosion Inhibitor on the rust spots that were forming on my car. The previous owner of the car did not take the car in for a faulty paint job recall, so now I am dealing with rust spots forming in many places. I sprayed this product on all of the spots and left it there. I did not ready any instructions to remove the product, so I've just left it on. It is clearly visible and sticky, but has not had any negative effects. Rain will wash it off eventually, but we've had a string of nice weather lately, so it's still on there even though I have still driven the car. Perhaps this product would be of better use on metals other than your car.

Does the job!

This is a very handy corrosion inhibitor to have around. It is great to use as a preventative measure. It helps to prevent rust and corrosion. I use this for my snowblower to keep it in good shape and stop corrosion.

Works great!

I used this corrosion inhibitor on some metal gardening tools and it does a great job at keeping them from rusting! This comes with a straw to pinpoint exactly where you spray it, making small spaces easy to reach as well. I sprayed this on some of my car parts as well to help prevent rust and corrosion. Over time, I noticed that the products I sprayed, stayed lubricated and did not dry up. It claims to protect metal from rust and corrosion for up to a year. So far, I am impressed with the quality of this product and its' effectiveness at preventing corrosion. I would definitely recommend this product.

Its wd40

What is there to say? WD40 works, it has always worked, and this particular version is no different in that respect. It worked very well on my kids bicycles over the winter. I am as always very pleased

Great stuff

I was really excited to try this stuff out as I've used wd-40 for years. I used this on a few rusted spots on my RV and it worked great, to get things moving and prevent further rust damage. A bit thicker than the normal spray, so it really got into where I needed it and stayed put keeping things going. I also used it to help clean up some old tools I inherited. Worked on pliers I couldn't get unstuck. Can't wait to try it on more things, especially once I get my summer stuff out of the garage. Excellent product that works!
