DuPont Non-Stick Dry-Film Lubricant Aerosol, 10 oz

This item was purchased to lubricate the rails on my garage door. It worked perfect. Easy to use. No issues.

I purchased the Dupont Teflon Non-Stick Dry-Film Aerosol Spray after performing a great deal of research pertaining to lubricants. To begin, my forte is cars, classics, and show vehicles, which I own. I seek only the finest quality products that are available to use mainly on my cars, as well as other uses applicable for lubricants. If the product is used on my cars, I will apply the lubricant anywhere. Dupont is a highly recognized company, being founded many, many years ago. Their technical expertise in technology, as well as the properties used to formulate such products remains unchallenged by any other company. The research of finding the proper lubricant for car door hinges was extensive. The top two products were both from DuPont. I decided to go with the Non-Stick Dry-film Lubricant over the secondary product from Dupont. This choice was made due to the fact of having a dry film coating rather than a liquid coating; my preference. Both products are highly rated. The aforesaid product will work best when applying over clean surfaces. This will coat any surface which creates friction, as to cover and protect all mechanical parts in a most exceptional way. I've only used this on car door hinges, trunk hinges and hood latches, and am extremely pleased with the outcome after only a day. The coating cannot be seen on a white vehicle and remains invisible. This is the aspect which I truly like. No gummy, or sticky substrate running down over anything. DuPont Teflon Non-Stick Dry-Film Lubricant is an exceptional product in which I will give a ten. Most will be hard pressed to find a better dry lubricant which again, remains invisible. The price is fair, and maybe more so than many other brands which claim amazing feats; "only at a far greater price".

Works well under my mowing deck

Works well, but it did leave some white stain on the metal.

I was confused by all the different non-oil lubricating sprays available, so I purchased a variety and tested them out to compare them against one another. I found that they all have different properties and are best suited for different applications. My testing was simple. I sprayed all the lubricants for an equal amount of time over an equal area of aluminum foil. I then monitored them all over a period of a week indoors at an ambient temperature of around 20C. Then I applied 100 grams of force to each test area and subjectively assessed the amount of reduced friction. (see photos) DuPont Silicone Surface Safe Lubricant. This contains silicone, Teflon, and ceramic boron. It remained fully liquid, thin, and runny even after a week. This seems ideal in situation where you have parts that require a liquid lubricant such as bearings, etc. Best to use this in situations where you would usually use oil, but when you cannot use oil-based products. DuPont Chain-Saver Dry Lubricant. This is a molybdenum and Teflon wax-based lubricant. This remained fully liquid, very thick and waxy after a week. This is formulated for bike chains, and I can see why. Ideal for mechanical parts that must engage and disengage repetitively. Another possible use might be for zippers or similar fasteners. DuPont Multi-Use High-Performance Lubricant. This contains Teflon and silicone. This is essentially a compromise between all the other lubricant sprays. It stays liquid and wet after a week, but is not a lubricating as the others, not as non-stick as the others, and not as friction-reducing as the others. If you can only have one bottle of non-oil lubricant spray, this is a good choice, but it is not the best at any one thing. Basically, like the WD-40 of silicone sprays. Super Lube 91110 Silicone Spray. After a week, leaves a very thin, nearly dry surface, incredibly slippery with the best friction-reducing properties of all the sprays I tried. Wonderful! Also, this is H1 food grade safe (ok for use in equipment used in contact with food). If you need to reduce friction on long rail and track mechanisms with minimal tackiness that might attract dust, this seems ideal! Super Lube 11016 Dri-Film Lubricant. After a week, leaves a dry surface, rather slippery in reducing friction and rather non-stick. This is also H1 food grade safe (ok for use in equipment used in contact with food). If you must have a fully dry film lubricant, this is my favorite! DuPont Non-Stick Dry-Film Lubricant. After a week, leaves a dry opaque white film. Not really slippery or lubricating against friction, but entirely non-stick. Essentially like Teflon PTFE in a can. In situations where you want a non-stick coating like PTFE, but using Teflon tape, etc. is not an option, this seems like an excellent choice.

I tried this spray on a horizontal sliding vinyl window that was squealing when it was opened or closed. It helped a little, but based on the reviews I thought it would slide like a dream. I put 4-5 coats of the spray on the track and it did slide smoother and the squealing was mostly gone. After that I bought a silicone-based spray and added it on top of the Teflon. That helped a lot. The squealing is totally gone now. I used the silicone spray on the other windows and it worked well. I also had a hand saw that I used for cutting tree branches that was quite sticky. When I bought it there was an oily lubricant on the blade and it slid smoothly. All the lubricant had worn off and once I cut about an inch into a branch, the blade would become stuck and it would be impossible to make further progress. I cleaned off the blade and added this Teflon spray, but it didn’t seem to help very much. WD40 helps to keep wood pulp from gumming up the blade but it wears off very fast. I also tried the Teflon spray on an old Miter saw blade that had started to burn wood as it cut it. Maybe the blade was already too worn for a lubricant to do much good, but the Teflon spray didn’t seem to help much. I bought a new blade and added the Teflon before using it. It works well, but then it is a brand new blade so it should work well.

Best lubricant I have used. I love that it dries instantly and leaves virtually no residue. Way better than silicone, WD40, or graphite. Have used to lubricate my digital lock and gate hinges that are exposed to ocean salt corrosion and restored function of corroded mechanisms. Works well on squeaky hinges without making a mess. Made my garage door, which was binding, open and close with smooth operation when i squirted it into the rollers and hinges.

Have used another brand of dry lubricant on my table saw cast iron. The manufacture of that brand loves it so much they put the price out of range. Found DuPont made the same product with an affordable price tag. Also has no additives that will affect finishes.

Buy only if the surfaces to be lubricated can be exposed while coating.

Bakwas product ....Don't buy
