- Aerol Dry Film PTFE Spray, Grade 7701 (300g/466ml), High Temp 250°C Lubricant for Food Processing, Packaging & Bakery Machinery, Non-Toxic Mold Release Agent, White Odorless Film

Over the past month, the "dimple" key was starting to get stuck while putting it into the key-hole and also when removing it. Since it is not recommended to use machine oil/WD 40 in locks... as they collect dust, I decided to order this. This does not come with an extension straw that can be used to spray into the keyhole... so sprayed it liberally on the key, inserted the key in the lock and shook it around to coat the internal pins of the lock. Repeated 2-3 times. Problem solved in 1 minute. The spray does not leave a thick white teflon coat on the key. The liquid that comes out of the spray looks clear and transparent. After it dries, there is nothing visible on the key. But it gets the job done... the key started going in without effort.

Actually it's just an aerosol spray like brake cleaner ..its has no lubricating material called PTFE in it.pls don't buy..and hope Amazon will take it back and refund my money

Company should provide the spray nozzle pipe.it's an absolute requirement.will reduce wastage to a great extent.the provided nozzle has a very loose fit.

Used for my car door locks (from outside, as well as behind the door panel). I do wonder about the amount of product in the can, vis-a-vis the amount of propellant. Did NOT come with any Extension Tube, or even a spray head that could accommodate one. The spray head appeared to be a regular spray head. I used an extension tube from an insect killer spray!!! :D (Dear Seller, please send me the Extension Tube and compatible spray head, for this product. Thanks.)

Compared to 3M price it's the best option , easy available Fast delivery Good quality

Concentration of PTFE is very low so no uniform film is formed only some white stains

Very good spray to lubricate surfaces and also protect surfaces from getting rust, like outdoor unit of A/cdoor handles etc.

If you are looking a PTFE lube for FEP then this is best just a bit overpriced My Recommendation >Spray from at least 20 CM away so it creates a uniform layer of PTFE >You will see a white layer once it's dries don't worry that won't affect your print quality too much (I run few test prints everything seems great) >Once you have sprayed don't rub it with cloth or tissue >As it creates a layer of fine powder rubbing won't help much it will clean the FEP instead
