1 JBGretschGuy 3 weeks ago I’ve been doing this as long as I can remember, but what I can’t remember is exactly who gave me the idea. I seem to think it was Rich Modica, who used to be Brian Setzers guitar tech. I use sewing machine oil and powdered graphite and mix it together into a sludge. Then I suck that sludge up into a syringe with an 18 gauge blunt needle. You can get those on Amazon under inkjet refill supplies.
