Paul, what if you glue or epoxy (devcon 2 ton or something) in the grommets before wiring, so that the glue acts as a buffer between the grommet and the paint so it doesn't chip. Once the epoxy is set, the grommets won't move when you wire it so the paint should not get chipped by the movement of the grommet..
