Good

7 days ago
Good for freeing up rusted metal and seems to leave a protective anti rust coat behind. Where it really shines is with the hose to get into small crevices and really get around all angles.

Yes, I recommend this product.

Cool feature

13 days ago
We have always had a can of WD40 in the garage for as long as I can remember. My partner was super interested to see that this one was specifically marketed as a penetrant for rusty bolts. It worked extremely well breaking the nuts free on a project truck that we recently rescued from a barn. Though we haven't used the flexible straw feature yet, it is definitely pretty cool. We were able to easily bend it into most any shape and deliever a spray just where needed. There's really no doubt that this will definitely come in handy in the future. The larger size can is an added bonus, so that we always have a bit on hand when it is needed.

Yes, I recommend this product.

Use it for everything

Absolutely love this, it’s great for working on cars. It does a great job of loosening up bolts and cleaning them up. I’ve had it for months now and i still got quite a bit in the can left.

Use of WD40 Products

8 months ago
I have been using WD40 Products for at least 60 years. Everything from kinds toys to BB Guns , Than Firearms, cars , home and Industry, and Aerospace. Just started using the penatrate, and it has worked well. It is a lighter penatrate than PB blaster, or Howe's penatrate. More like CRC ultra penatrate. I have been using this on a restoration job on a 5 Ton portable crane. Working great on the rusty hinges, and latches. Control cables and switches. Next , I will try it on some of the bolts that are bigger than 3/8". I have been testing WD-40 And these other penetrates on this job, seeing which one works the best , for each lube problem. I am placing manufacturers Product decals on the 5 Ton Crane, showing which products are being used in the restoration. I am also , videoing this project for my YouTube channel. Matthew Spence @ MuseumMatt. I need some WD-40 Decals

Yes, I recommend this product.
