Would it be possible to get a closer look at the back of the camera sensor, or more importantly, how the cables connect the sensor shifting mechanism to the base frame? It’s quite possibly the one of the most interesting engineering problems in it and I can’t seem to figure out how it works from the photo above - would anyone be able to explain or share more detailed images of this mechanism?
Okay so after looking, the closest thing I could find to the blue or green stuff is TG-PP-10 from t-Global on DigiKey. It’s 10 W/mK, so probably a good bit better than the blue or green stuff which is usually 1-6 W/mK. IIRC other manufacturers of this stuff are Bergquist (now Laird?), Henkel, Dow Corning, but t-Global sells the most reasonably priced one for small quantities at just 28$ USD for 50 grams.
Common search terms that might be helpful are “thermal putty”, “silicone thermal putty”, “one part gap filler”, “gap filler”. among other things like that. Many of these are non-curing, so if you carefully scrape what you have into a little mound, you may be able to reuse it.
