It seems like everything you do on a gig would dry out your fingers.
You can go dry route with the roll on powder I got that from GraphTech it works really well but it leaves powder stain everywhere.
In general I use FingerEase spray. It works really well. That’s my go to.
In a pinch just use your nose grease works better than anything.
Here’s the discussion we had here a few moments back. Thanks for @joergkutter for the video.
