Rated 5 out of 5 by from Wonder product! I have been using WD-40 for years. It can be used on door locks, rusty door knobs, car door locks. It is a great lubricant for locks because it does not contain graphite, which wears the inner mechanisms. I have even used WD-40 on fish bait for catfish! WD-40 makes my replacement windows easier to raise and lower. WD-40 makes rusted screws loosen. Also loosens lug nuts on automobile tires. I havde a can in the house and in the trunk of my automobile. WD-40 is truly a wonder product.

Rated 3 out of 5 by from Use it for Scooter maintenance I brought it for lubricating rubber components for my scooter. Here is my experience with this product. 1) lubricating properties is good and lasting. 2) doesn't swell rubber like oil base lubricant. 3) does help in preventing bolt and nut from rusting but don't expect miracle in tropical environment. 4) doesn't dry in seconds as advertised. Days later it still wet. Might be the silicone oil left behind. 5) smooth out my scooter brake master cylinder piston when it get rough. 6) use to prevent rust for battery terminals and bolt and nut. 7) use to prevent front fork and rear suspension from squeaking. If you need a dry silicone spray, look elsewhere. If a good and slow drying lube that is safe on rubber is what you need, you can look into it.

Rated 3 out of 5 by from not great for speed cubing Wd 40 silicone spray seems like it would do well with mechanical and automotive applications, however it just doesn't live up to the standard set by crc silicone for speedcubing purposes. Not great for lowering static friction (although once the parts get moving its pretty smooth) and the quick dry claim is simply not true. You would think anything dissolved in propane and butane would dry in minutes at most, but I let this sit in open air for HOURS and there are still wet spots. I'll hold on to this for future automotive needs but I am going back to crc for any cube lubrication

Rated 2 out of 5 by from Smart straw was not useable I just bought this to use on a hinge and the "smart straw" broke immediately. when I flipped it up an o-ring fell out and when I took it apart I noticed holes were missing in the plastic piece so it was unuseable.

Rated 5 out of 5 by from Great product for my fifth wheel hitch I apply WD-40 silicone lube to the moving parts of my fifth wheel hitch. Since it's water proof, it doesn't wash out in the rain like other lubricants. I only have to relubricate every three months or so.

Rated 5 out of 5 by from Works on Guitar Nuts! Heard this worked from a Guitar magazine as I do a lot of modifications on electric guitars. Put this on the nut (the string positioner at the top of the fretboard,) and it works way better than the old standby Graphite, and for sure it's less messier. In fact, it even removed some of the Graphite mess left behind the previous time!

Rated 5 out of 5 by from Great product. Used to lubricate the weather stripping on my car's window, which was dry and dirty, preventing the automatic closing of the windows. Just a quick spray worked perfectly! Great product.

Rated 5 out of 5 by from Litter Box After years of cleaning sticky cat poo from the box and scoop, I sprayed both with the WD-40 Silicone to see if it would help. Yeah! No sticking to the sides of the box or to my new stainless steel scooper. Anything to make this job easier is definitely worth it. Now I'm having fun testing it on other problem areas like the sliding door tracks that drag, trash can liner, etc.

Rated 5 out of 5 by from Works like magic !!! I used " WD-40 Specialist Water Resistant Silicone Lubricant " to hide the clear coat damage on the roof of my 1989 Lincoln Mark VII. It worked like magic. I can't see the damage anymore. I thought I would have to get the roof painted to fix the clear coat damage. I just spray some Specialist Water Resistant Silicone Spray on the damaged clear coat, and wipe away the excess. Poof like magic the damage is gone.

Rated 1 out of 5 by from WD-40 Silicone Lubricant spray problem I bought this two days ago and no matter how I position the nozzle, spray comes out every way EXCEPT through the straw.  Terrible design!  What a mess it made on my shirt.  Would recommend this product if it wasn't for the poor design.

Rated 5 out of 5 by from Great for RCers I use this on R/C cars to clean and protect the parts after a hard day of getting dirty and also to clean out and lubricate the ball bearings. Works beautifully.

Rated 1 out of 5 by from Smart straw does not work No matter what position the straw is in, the fluid does not come out the straw and flows around the trigger. I had to apply the product with a paper towel. What a mess and a waste of $5.00.

Rated 5 out of 5 by from Hardcore suspension componets and lube maintenance I have an 05 Subaru Wrx STi with lots of suspension modifications... Many bushings are suspension components are upgraded which causes the suspension to squeak and make noises. WD-40 Specialist silicone spray was what my OEM rubber bushings needed to re-lubricate them and take away my noises... Perfect for the do it yourselfers ... NOTE: This is only for the OEM rubber not polyurethane bushings...

Rated 5 out of 5 by from Outstanding protection in damp climates This is a phenomenal product.  I live in a high humidity climate and this is the perfect lubricant.  Screen door hinges that face salt water won't squeak at all and they won't rust when you use this

Rated 4 out of 5 by from I like it more and more I've used it on a ball joint that is wet most of the time, as well as on a sliding mechanism that has metal on metal. So far so good, and it's lasted longer between applications than I expected for a silicone product.
