Thread Sealants question!

Has anyone ever used any of the following products?
I was just introduced to the following products by a Jet Lube sales rep and I was curious to what others thought.

- Petro-Tape
- TF-15
- No.60
- V-2

I've never used any of these products but I am always interested in finding a good new product. Any feedback is really appreciated!

I use the old gooey pipe dope. I find it so much easier than using tape. It is messy, but it's not too hard to clean up. I'm not saying that it's the onlything that is any good, but it works well for me and it's cheap.

Sounds like more spam setups...
