What would you guys do about this surface rust on the back of my rally speedometer. Or just ignore it. I don’t want to make a mess or damage it, but I’ve tried to stop deterioration on everything I’ve touched so far.
Auto body scuff pad. You can cut them into small pads to use with a hemostats. Then get some self etch primer in a spray can and spray some in the lid to use with a brush. Use a brush and brush it on carefully watch that it don run around and get on the face. The acid in the self etch primer will adhere and stop the rust. I just did one for a rally dash. Painting over the primer is not necessary it won't see sun light.
