I learned about this product while working at my oil gas job. Don't use that crappy white Teflon junk. This works 100 times better with very little product. Good for air lines and water lines.

I used it on SBC to seal head bolts. Went on smoothly, torqued easily and let it dry for 24 hours

It's nice and works very well, but it's a little thick and because of that not always easy to apply.
