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

I am using this to keep wet snow from sticking to snowshoes and it is working perfect at about 1/4 of the price of aerosol ski wax.

On one hand, it's got forever chemicals in it. On the other hand, it works so well to lubricate and/or protect almost anything you can imagine, and the three pack of 14 oz cans is such a bargain! It's both cheaper and better than WD40 (10 oz) specialist dry lube, IMO. It has (hexagonal) boron nitride in it which is a high temperature lubricant, in addition to teflon, and NO silicone. You can use it on saw blades, drill bits, window tracks, gaskets, "tight tolerance metal on metal," wood, etc., etc. (See the product description.) I just made a wooden jig for my track saw and sprayed some on it, and it helped!

Works well under my mowing deck

Exactly as described, dry lube. I used on the zippers on my jeep soft top. Doesn't attract dirt.

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.

Great product. I used it to coat my snow blower shut. Sprayed the shut twice during the winter season. The slushy snow flew out of the housing without excessive jams. Better yet, I went through the entire season without a shear pin malfunction.

I purchased this Dupont non-stick spray after two seasons of scraping the deck and leaving clumps of grass in the yard with my Toro Recycler mower. I pressure washed the blade and underneath the mower deck and let it dry before application. Next mower I buy I will treat before first use but that’s for another day (had I only knew then what I know now) After the deck dried I applied two liberal coats of this teflon spray letting it dry between coats. I have to say; I AM AMAZED!!! Not one blade of grass stuck, clumps of grass usually littering the yard were almost non-existent and I swear it seemed like I used 1/2 of the gas I normally do. I attribute all these positives to the Dupont spray that allowed proper air flow for the mulching feature, no bogging down and no clumps due to the slickness of the spray and lack of friction on the mower parts. If you haven’t guessed yet I kinda like this product. I mowed my approx 10,000 sq ft yard with no sticking of any grass clipping whatsoever. I look forward to seeing how long this stuff lasts before I have to re-apply. Happy mowing!

I’m not sure how good it is for other uses but used it on a squeaky front door hinge and it seemed to work after removing all pins, cleaning, spraying, letting dry and reinstalling. Less than a month later it’s squeaking again which is disappointing.
