I may be able to get some. If anyone has some, and a perfectly clean copper plate, it would be good to wipe a film over it and wait 2 weeks and see what happens.

My original experiments with the WD-40 involved a brass sheet with two bare steel nuts screwed to it, one as a control, put outdoors in a rain protected area. I found that the rust on the steel was very well inhibited by the WD-40, but it produced spotty corrosion on the brass. Then I tried a range of metals and found copper the most sensitive to the effect and the brown spot effect is seen indoors after 10 days to 2 weeks. So far there is still no issue detected with the RP7 or Inox mx3. I'm also repeating the experiment with a much thicker coat of RP7.
