>>How'd the furnace paint hold up?<<
I recall having baked it in my oven for awhile ... having grown up watch television adds about "baked-on automotive enamel" for $39.99
The SP in my avatar photo shows the results after a lot of years of regular use. Instead of brassing, it's "chromed" around all the edges, plus a bit of wear on the frontplate, under the focus wheel, where I tend to hold the camera. For a camera with light and infrequent use, like, my S2, it has held up extremey well.
Overall, the two well-used cameras have a kind of grungy look that I prefer. Makes people stop worrying that they might be in the presence of a very expensive camera. I was using the well-worn S3 to take some pictures at my daughter's Girl Scout cookie sales booth. The mom in charge -- a well-to-do-lady with expensive tastes -- saw the camera and craned her neck to get a better look, asking if it was a Leica. This happens every now and then. My standard response is, "No, it's just an old Nikon from the 1950s." To which she showed visible relief and immediately stopped obsessing about the camera.
