This general procedure is recommended to prepare an aluminum surface for correct electrical bonding.
1. Clean grounding location with solvent.
2. Remove non-conductive films or coatings from the grounding location.
3. Apply a chemical conversion coat such as Alodine 1200 to the bare metal.
4. When the chemical conversion coat is dry, clean the area.
5. Install bonding equipment at grounding location.
6. After the bond is complete, if any films or coatings were removed from the surface, reapply a film
or coating to the surrounding area.
Refer to SAE ARP1870 Sections 5.1 and 5.5 for a more detailed procedure.
