Terrific stuff. McMaster Carr sells it for around 7$ a tube. It is high temperature silicone sealant with a twist... It resists gasoline exhaust great. I used NordLock washers several years ago along with the PUC, but have since moved away from NordLocks favoring PUC alone.... NL not needed. Try it...
