Is Metal Rescue GEL safe to use on painted surfaces?

Created by Matt Bender, Modified on Tue, 28 Jun 2022 at 11:11 AM by Matt Bender

Yes, GEL is safe on the vast majority of paint coatings, with a few exceptions.

  1. If a layer of rust has formed under the paint some of the paint coating will be lost as GEL removes the rust and therefore the paint on top of the rust.
  2. Some paints and inks (typically red/orange), especially old paints, may use iron oxide pigment. GEL has been engineered to remove iron oxide in all forms, therefore it may dissolve the pigment in these types of paints.
  3. Painted metal items with flaking or cracking surfaces or chipping/deteriorating paint or coatings may not be suited for rust removal--whether it is GEL or a different product–and may experience unexpected damage. If in doubt, test a small area prior to full application.
