Dupont's Spray on "Teflon non-stick dry film lubricant" - anyone use it?

I got a can of this stuff a few years ago and it is some pretty interesting and useful stuff! I recently noticed that it is a "lubricant" but I have rarely used it for such a purpose as I've used it where I need a teflon coating on something to make substnaces slide off easily.

Here is an add for the product - it does tell you most of the things you need to know about it, and it states that it is good till 490F!

I've used this on snow shovels, snow blowers (the chute where snow - especially heavy wet snow - accumulates, as well as the entire "collection/scoup" area inside which the blades turn - the not often stuck to most metal areas within the snow blower and this spray has made a complete difference, the snow just falls off - no more buildups!). The main reason I bought this was for making soap molds where I needed the molds to easily release the soaps after the have "cured"/hardened. The molds had been coated in a 2 part epoxy of BPA and Epichlorohydrin (I can NEVER remember this word, any suggestions how?) and then sprayed with the Teflon lubricant.

The spray goes on clear and it MAY leave a light greyish white look that seems a lot like dust and can be removed with a dry rag. The spray remains stuck on the medium but excess can be removed.

The can has a different design now and looks like this and is about $12-14 for 14oz (lasts a LONG time).

There is another product called 'Teflon Penetrant Spray" and it looks much more liquid and "oily" than what I listed. The video shows it being used to restore/remove rusty things and stop new rust from forming also helping make stuck nuts/bolts easier to remove. It looks like a mix of WD40, oil and teflon, though IDK.
This stuff is about the same price.

So I'm wondring how this spray will hold up against gaseous HCl and ammonia, I know PTFE is resistant to both, but as for the spray, IDK. I'm considering coating the inside a 3/8" ID copper pipe which will run from my boiling flask to my condenser among a few other uses where coating the inside of glass tubing would be very beneficial in cleaning afterwards.

I was also thinking of coating my rubber and cork stoppers with this and seeing what happens, if they are more resistant to the hot HCl gas or not. I figure it can't hurt to try and maybe something good will come of this experiment!

OH, it also does an AMAZING job on squeaky doors, especially car doors, a little spray in the hinge and 5+ years later still no squeak, where I was doing it about 2x a year with a silicone/cate base dry/spray lubricant and the Teflon stuff is about 1/2 the price!
