WD-40 Specialist Penetrant with Smart Straw, Penetrant for Metal, Rubber and Plastic Threads, Locks and Nuts, Industrial Strength Fast-Acting Formula, 11 Oz.

2011 2500 HD, 180k miles, ORIGINAL shocks and Minnesota rust awaiting me. As you can see in the picture a lot of rust. I wish I took before pictures but just imagine so much Rust on the bolts that I could barely see the outline of the bolt against the hanger.I sprayed the WD-40 on early in the morning and let it sit for about six hours and then did it again on all four bolts. In the evening time I started the job that I thought would be a nightmare ready to fight the battle.I was using good quality impact drivers, which certainly will help but nonetheless, I expected the worst when I started cranking on the bolts. To my astonishment, all four broke free pretty easily and came out practically like New.This stuff works!!I replaced both shocks in about 20 minutes with only average levels of discomfort. Considering how they looked before I honestly can say I was astonished.Must have. Get it. Soak it. Enjoy it.

WD-40 did exactly what it was supposed to do. I used it to fix a squeaky fan that had been driving me crazy, and within minutes the noise was gone. Easy to use, super effective, and a must-have for quick fixes like this. Great product!

This is the greatest stuff!!!!!! I am a 75 year old grandma that had major back surgery 6 months ago and home repairs had been piling up. This "specialist" wd-40 loosens rusty nuts and bolt like magic! Yesterday I fixed my 12 year old lawnmower and now I am changing out a bathroom faucet that was installed in 2007 My son in law couldn't even loosen some of the water hoses, today I squirted them with this Specialist WD-40 and I got them all disconnected. Only problem is that the spray button is very hard to push, it takes both hands to press it down! I am buying more cans of this (so I can spray the top of the can) Very low odor!!! The can empties pretty fast! I cannot believe it is cheaper than regular wd-40. I am ordering two more cans this time.

Great. Spray in crevices to deter spiders. Helps. Also stops squeaking doors and hinges

For most equipment requiring lubrication, WD-40 is fine. Where it isn't the best they tell you about. For example, I need to lubricate my sliding glass door bottom occasionally. WD-40 only works for while - Vaseline works longer, but it's use for something like this is noted. One big beef though is that the spryer mechanism on my my last three cans of Wd-40 failed before the end of the product! Thus the 4-star and not 5. Carefully read it's uses and ensure you are using the right lubrication.

I have used this product for several years. It is good for loosening screws that are stuck. Excellent for eliminating squeaks. I always keep it around to use around the house.

Why did you pick this product vs others?:Needed something stronger for stubborn rusty bolt removal. I let this soak overnight and nuts zipped right off. Low odor too!

Did the job for a few things, worked wonders for my kubota, I have an older zd28 and the fan belt went to heaven, lol but had alot of cranky bolts that this stuff took care of, great product!
