I selected this product as a release agent when casting concrete using raw wood as a former. Two thin coats within an hour of pouring was quick and easy. After overnight curing, the wooden formers were easily separated.

Was recommended this product on a car forum for curing creaks and squeaks. Had tried other lubes in the past but to no avail. Used this on all the moving parts (theres a lot in an SLK) and have been amazed at the results. The car is almost silent now, just a couple of very faint creaks to track down. Top product, I was not expecting it to be this good. Simple and easy to use, although watch out for over spray!All in all great product and excellent service from Haverhill branch (as always, polite friendly and very helpful)Thoroughly recommend both the product and the Haverhill branch!

Had a few squeaky hinges around the house that needed sorting out + the built-in fridge/freezer door plastic slider guide was making a bit of a whine every time we opened it. Worried initially about discolouration of white plastic and smell around the food, but thankfully no such issues. The folding nozzle is genius. On to the bikes and padlocks next...The only criticism is that a canister of 1/4 of current size would suffice for years for most households, so considering a smaller one might be a good idea.Price was also better than competitors.
Used this product on the minivan door rails on the bottom, middle, and top, and I haven’t been disappointed. Holding up well for the last few weeks. I haven’t checked the manufacturer recommendations. I’ve also used regular WD-40, and that seemed to wok just as well, but it doesn’t have the thickness of white grease. I have the base model so no automatic side door opening.
I was recently stranded when my car's remote key fob stopped functioning (not the battery in it). I keep the actual key handy; however, it had been so long since I'd actually used it that the locks had frozen. AAA was suggesting a 4 hr. window for showing up, and the nearest car dealership where I could purchase a new remote would have been closed by then. I'm lucky in that the lock-out happened not on a remote road but at a shopping mall. I figured I was in luck when I saw Harbor Freight's sign. Sure enough, they had this silicone spray, and it worked immediately.Fortunately, I did not listen to the salesperson who thought your store didn't carry it. The only negative is the size of the can. I think this would be handy to carry with me for just such emergencies if ... MoreI was recently stranded when my car's remote key fob stopped functioning (not the battery in it).

I think this would be handy to carry with me for just such emergencies if it were a small size. Even using it when I got home on a squeaky door hinge, I still think it will take forever for me to use up such a large can. Bottom line: excellent product
I bought this to repair my pure blue H2o Reverse Osmosis unit.I had previously purchased some storage containers with the translucent lids (so you can see your parts)I was having great difficulty removing the label adhesive so I could actually see the parts in the box.First I tried isopropal alcohol and then some electronic quality isopropal alcohol. The sticky wouldn't budge.On a whim I tried the "Specialist" wd40, to my dismay All the glue came right off and left me with a nice clear storage container top.
In spite of vigorous shaking the product appears to be mostly propellant. What emerges is very thin, almost drippy. I cannot compare it with alternative aerosol products but I found it disappointing.

however in the process it caused severe wear to the guide pin bores and guide pins, I discovered many many years later my mistake, use a pure silicone grease only.One of the additional spray lubricants i have purchased for use is, WD-40 Specialist High Performance PTFE spray 400ml.Technically WD-40 Silicone spray should be the correct grease type for the brake guide pins application then.NO, the WD40 silicone spray lubricant contains other oils and chemicals in addition to the silicone component, this applies to all spray lubricants, in addition it is a spray oils lubricant, and not a grease.It will destroy the butyl rubber gasket seal on the guide pins and possibly the caliper piston seal if it contaminates it, this applies to all spray oils and greases.In this instance, for clarification purposes I first read the data sheet available for the silicone spray on WD-40's domain website, apparently the effect on other substrates and materials has yet to be clarified!Then i tested the WD-40 silicone spray on an old calipers guide pins and pistons rubber seals, the end result was that the seals swelled and expanded making them loose fitting and ultimately useless in sealing their intended components.Does this mean that you should stay away from this or any other spray lubricant or grease?No, as mentioned at the beginning these lubricants are designed for specific application, just ensure you do not accidentally contaminate another non compatible plastic or rubber.Use the correct tool for the job, and if in any doubt test and or read the sprays technical documentation.So how does the WD-40 Specialist High Performance Silicone spray perform.Unfortunately i have yet to use this spray on an application, however I have used the WD-40 PTFE, and also the standard WD-40 anti seize spray many times over the years with excellent results.The standard WD-40 lubricant has always performed superbly on difficult to remove and stubborn nuts screws and bolts, as well as other applications.Their is no reason to believe that the WD-40 Silicone spray will not perform as well.The spray will apply just as precisely and easily using the available built in straw, and also provide even and good coverage if using the built in wide angle nozzle option.I tested the silicone spray and it dries to a tack free finish, which will help significantly in preventing clogging and sticking issues, as well as repelling excess dirt and dust contamination.It will last a very long time, as their is sufficient quantity in the can for many applications to be applied.Toolstation themselves has become one of my go to stores over the years for many items I have required, they are very competitive with their pricing, and have always provided a highly reliable service, in addition the stores advisors have always been helpful and courteous when i have visited the store directly.As such they remain one of my favourite suppliers.
Bought this initially to stop my car's electric window squeeking which it has done fabulously spray a little along the weather stip operate window a few times then clean the window removing residue. Also sprayed some on hinges that were noisy they are quiet now
