Through the years we have learned the only true way to remove all rust is to completely submerse the entire body and panels into a non-acid solution that is an environmental-friendly cleaning process vastly superior to the alternative cleaning methods that damage metals from harsh abrasive blasting or acid dipping.
Once the car is electrolytic immersed, a negative/positive charge is applied to the metal causing the metal pours to open and close enabling the solution to clean deeply into the pours of the metal. The final rinse is a combination mix of water and phosphate leaving the metal with that gold blue look. The cars return to us as clean canvas where only then we are able to assess in detail any work needed to be done on the body. Most importantly though, ALL the rust is gone and never to return. The car is now ready for a two-part epoxy coating used seal the metal.
