There's nothing I've tried to date that works as well as 'Woody's Arrow Lube".......don't know what's in it but it's the best.
It comes in a little jar with a roll on style felt applicator.
Good ol' pure Ivory bar soap works great but is a pain to keep handy and applies kinda crappy.
I've tried all the supposed good stuff, Slick 50, Armor ALL, Silicone ,yadda yadda and they aren't close to Woody's.

Won't leave home without it especially with carbons blazing at 300+.
