I am working on my 1967 XR7 gauge cluster (replacing the 2-wire tachometer with a 3-wire), and while I have it apart, I would like to get this surface rust off the gauge face. Any tips for how to clean it off without messing up the paint?
I wound up using some phosphoric acid on a q-tip and then followed it with a mild degreaser on a separate q-tip. It certainly isn’t perfect, but it’s a bit of an improvement. Thank you for the replies.
