Im currently doing a restoration project on a RG2120x, hoping to make my favorite guitar shiny all over again.

But I have a problem with the rusty and bubbling saddles on the bridge. I guess a normal Lo-Pro Edge could easily be replaced but this particular model has a piezo on each individual saddle. The piezo saddle itself no
rust, just the piece holding the string behind it is rusty. I have 2 options to ask if possible-
- replace the rusty piece behind the piezo saddle with a standard one?
- Remove existing cosmo colour then repaint and apply a protective coat above it?
Thats all i could think of and im not sure if its possible though. I tried sending to a nearby tech but he just pretend he didnt hear my problem. Really stump now. Any advice would be great.
