I know what your talking about, and I think there is PTFE in it. There is NO PTFE in Molly Lube. I have also used (Liquid Wrench Dry Lubricant) with/con (Cerflon) it is also a Dry-Film with no oil residue. Wal-Mart also has this and it's only about $5 compared to Molly Lube wich is about $35 a can. But for me the Molly Lube is what I use now. Im not sue how long it has been around, I just started using it about 3 years ago. Anyone interested in it, look it up, you'll be suprised what this stuff does. BP
