1. Is the rust in a corner or around one of the rivet/screw holes?
2. can u wipe it off with distilled water?
If the passivation layer(the outer coating) is scratched or missing then the case will eventually need to be replaced but if its just rust on the surface with no scratches then you shouldnt have too much of a problem. Either way i would contact heartfelt and they should fix it up for ya, they have very good customer service
