Denis Wick Valve Oil with PTFE (Teflon beads)
Valves do not stick, even when completely dried out.
Hetman's #7 Slide Gel
Does not oxidize and turn brown.
Convenient squeeze bottle helps in laying down a thin bead.
Thanks to all that recommended the Hetman's #7.
I have used both exclusively since receiving my new Besson 2056 baritone.
Excellent combination, especially for new horn break-in.
