You may wonder, “How much rust does my car have?” Well, there is only one way to find out, strip it down to bare metal and take a look.
How many times has the classic car buyer been told, “This car has no rust.” Come on guys, we’re talking about 20, 30, 50 year old cars, of course they have rust. The question should be how much and where is the rust and what can be done about it.
Since most rust is hidden under body filler and paint chemical stripping is our method of choice for rust removal. E-Coating, an electrically applied sealer is then used to seal the bare panels to prevent rust from coming back. This gives our clients the peace of mind to know their restoration will stand the test of time.

Z- 28 Chemical Bath and E-Coating Process Complete
Sheet metal parts are baked in an oxygen-deprived oven at temperatures of 750 – 800. The oxygen-deprived chamber is to prevent warpage. The oven bakes contaminants, paints, and any material other than metal into ash. A pressure wash with water follows the oven baking procedure.
The metal components are then dipped in phosphoric acid. This is a 10% solution used to remove rust and substances turned to ash in the oven. The panels are all pressure washed with water after this treatment.
The metal components are then dipped into a hot caustic soda bath. This bath is to neutralize the phosphoric acid. All panels are then pressure washed with water.
The metal components are then dipped in an electrolysis “de-rust” solution. This bath is also a low content caustic soda solution. This process removes rust and returns a bright sheen to the metal. All parts are pressure washed with water following this bath.
The panels are then treated through electro deposition. This process is sometimes referred to as E-Coat or E-Coating. It is necessary to seal the cleansed metal and prevent corrosion on all surfaces from the inside out. This is also a liquid and electric process. The parts are rinsed. The parts are treated with zinc phosphate for corrosion protection. This is a submerged electro plating process. The parts are rinsed. The parts are de-ionized. The parts are rinsed. The parts are positively charged and submerged to receive a Cathodic Epoxy Coating inside and out. This coating prevents rust and promotes paint adhesion.
