Is Metal Rescue safe to use on painted surfaces?

Yes, Metal Rescue will not remove or harm the vast majority of paint coatings. However, if there is a layer of rust under the

paint some of the paint coating will be lost as Metal Rescue removes the rust. Also, some paints (and inks) may use iron oxide pigments (usually orange or red). Since Metal Rescue has been engineered to remove iron oxide, it may dissolve the pigment in these types of paints. It is always best to test on a small section or hidden area prior to use.
