Hank, this is from Richard, no final word yet and I’ll put it up when he hears back,
I have a call into tech colleagues at Stew Mac and GHS to find out if Gorgomyte has any downsides or interactions with SCGC finish or materials. I trust Stew Mac’s vetting standards so that’s an implied recommendation for general use of Gorgomyte, but not necessarily an ok for contact with nitro cellulose lacquer. In the meantime, here’s a link for ratings of the top 10 fret polishing products.

A the best,
