Royal Purple 15000 Maxfilm High Performance Multipurpose Synthetic Penetrating Spray Lubricant - 11 oz. (Case of 12)

The headline shows what I find most impressive. I've always had issues with my sliding screen door sticking and spray grease/WD 40 works for what seems like minutes. The other day I went to use the screen door months after applying Royal Purple and accidentally threw the screen door hard into the jam because I anticipated heavy resistance and instead it flew open without any problem. Similarly I was having issues with the key in my front door getting stuck. I honestly thought the key was bent but decided to give a quick spray in the keyhole. Since then my key meets zero resistance -- again months after application. A couple times I've used this on areas I couldn't find the source of a squeak - a desk chair that rocks and my trucks parking brake pedal (just the pedal - not the brake!). I sprayed RP on these and disappointingly the squeak was still there. After a period of time had passed I suddenly realized the squeaks were gone! Even though the issue wasn't resolved immediately the lubricant made its way through the components and ultimately resolved the issue! Though expensive, it's totally worth it for the DIY home owner.

This product works great someone sprayed it on a sticking tailgate. Had to have some

It works just like any other penetrating oil except 10x better.

This is the best lubricant I'd found in a can. It penetrates into crevices to oil the thing you're actually wanting to oil instead of just the outside. This can last a while, you don't need to use much.

Great lubricant for almost everything. I’ve even used it on stuck bolts.

Excellent penetrating juice that provides super lube characteristics. Many other products will "free up" moving parts, but this provides a superior level of lubrication as well. I've used it on several projects, including 2 La-Z-Boy chair mechanisms that were very stiff and had some rust; the chairs had been unused for 20 years. They work like brand-new now! I've used just about every penetrating/lubricating product on the market in the last 40 years. I'm a retired automated printing press mechanic/technician, and I wish I had this stuff available years ago - would've saved countless hours on the job trying to free-up sticky parts that were difficult to reach. Although the cost is high, a little goes a long way. The only improvement would be to use a screw-on nozzle instead of the push-on "straw" which tends to fall off if you bump it. However, the quality of this Royal Purple far exceeds this inconvenience. (From what I understand, WD-40 was developed as a Water Displacement product for ignition & electrical systems - hence the name "WD". It provides minimal lasting lubrication, and needs to be re-applied frequently.)

been using this for years, forget WD-40 etc. this is the ONLY can you will use and absolutely hate it when you run out. I use this on everything. doors, rollers, you name it. worth every penny.. I would rate this higher than 5 start if I could.

Had never used RP products before. Had decided to try some RP high performance grease for my HF spring compressor, and saw this advertized. After reading the reviews I decided to give it a try too. Must say I have never really been happy with WD-40 as a penetrant/ long term solution for anything. I have an old Stanley spokeshave tool I acquired at a garage sale I wanted to fettle up for use. It has a metal body which was was pretty rusty and with a couple of very tight rusty screw type blade adjusters. I sprayed it up with the RP maxfilm and left it sit a few minutes - very quick dissolution of the rust, and freed up the threads very nicely. Very impressive. I replaced the beat up old Stanley spokeshave blade with a wicked sharp Hock A-2 cryosteel blade and the tool is good to go to shape the neck for the ukulele I am making. Wont be buying any more WD-40 - this is way better.

浸透力がすごい。

Awesome!!

旧車の固着したキャブレターに556を吹き付けてもダメでしたが、30分でビスヘッドを舐めることなく回りました。 やはりいい道具は仕事します。

I love this stuff -- wish there was more varieties available!

It's lube. It lubricates things.
