What sort of paint would you recommend using for minor touching up of small scratches on the back of the Olympus XA 2?
The surface of the XA is a rather special baked-on surface with a semi-matt surface. It’s hard to make a touch-up without it showing. I think that whatever you try will end up looking worse! Why not just treat the scratch as a trophy. My best XA2 has some scratches gained when I slipped on some rocks in Italy, and I thing of that holiday whenever I handle the camera.
