I dont even keep ptfe tape on the van.
What do you use for rad valve tails OOI?
Most of the stuff I do is replacing existing and it takes 2 seconds to 'beef up' the old olive with a bit of ptfe.
Less messy and easier to carry in the tool box.
Probably a liquid ptfe or loctite 55., had to buy my first rolls of one wrap and ptfe in years a few weeks ago because an underling nvq graduate was panicked by the stuff. Worrying really.
And those sh1tty plastic rolls are neither tidier or easier when they break into dozens of pieces.
