Your vehicle is subject to corrosion thanks to humidity and other elements that may cause oxidation on metal parts that are not properly protected. For those who are concerned about keeping their vehicle sound, the proper rust protection corrosion control methods can help extend the life of your vehicle.
What follows are some tips on when to employ such corrosion control methods and how to get it done properly. This is recommended for all vehicles.
Primer Corrosion Control
If you are going to add rust protection to your vehicle in the form of painting, then it is advised that you place primer on the metal surfaces first. 2K epoxy is recommended to be applied first to all bare metal surfaces before you use other products such as body filler or seam sealers.
The primer not only protects the metal but provides the proper surface for the paint to stick. A primer can be brushed, rolled, or sprayed onto the metal surfaces. 2K urethane primer or epoxy is recommended thanks to its inherent strength and durability. Just be sure to apply the primer to parts that are separated from the vehicle first.
Seam Sealer & Undercoat Rust Protection
Once the primer is applied, then the seam sealer can be applied as well to the appropriate parts. The sealer itself must be used over the primer and not come into contact with the bare metal. As the name implies, the sealer will address any seams in the parts so that they are properly protected.
The undercoat is applied to most areas under the vehicle, although it should not be applied to the exhaust or components that move. In addition, a weld-through primer is often put down first to provide additional protection. The right weld-through primer should carry plenty of zinc which helps slow, if not stop the oxidation process.
- Wipe away excess when using weld-through primer to bare metal surfaces
- MAG plug, butt, or MIG brazing should not include weld-through primer
- After MAG plug, butt, or MIG brazing, apply epoxy primer over joint in weld
The last step before completing the corrosion control process is the application of cavity wax inside any panel that was welded. You will most likely need this verified by a quality control inspector who will examine the vehicle.
The cavity wax needs to cover all recommended surfaces inside doors and other areas not normally covered by paint. Auto shops that use cavity wax should be going through at least one can per technician every working week for ultimate corrosion control.
Remember to double-check your work to ensure that all surfaces are covered. All it takes is one open area on a bare metal surface to start the oxidation process.
When you use the right rust protection corrosion control methods on your Vehicle, you can protect the metal parts on your vehicle. The result is avoiding rust issues that may cut short the life of your vehicle or avoid major repairs that may be quite expensive. A little rust protection today may prevent the corrosion, then the replacement of valuable parts tomorrow. For more information contact Stephen at Rust Bullet for details.
