Rust-Proofing Application Guide

 

Basics

  • Areas which must be covered are all those with folded or welded sheets such as bottom and corners of the doors, front and sides of the hood, bottom of the trunk, bottom fenders, etc.
  • Usually, most hollow zones such as the footboards are readily accessible by holes already present on the vehicle. In the majority of cases, the vehicle must be lifted to gain access to these access holes.
  • At times it must be necessary to make holes in order to access certain areas. In these cases, make sure to use a fuse designed for this purpose and coat the inside and outside edges of the hole with rust proofing and install a plug.
  • If the structure of a vehicle is unknown to you, it would be wise to consult an experienced body shop to identify and treat the particular zones of the vehicle appropriately.
  • In general, it is not necessary to apply rust proofing on flat and non-exposed surfaces such as the center of the hood and the trunk cover.
  • When treating hollow areas, we must increase the pressure of application and rotate the stem in all directions to cover and saturate all surfaces. It is always better to apply too much than not enough product.
  • The areas under the decorative appliqués (especially on the underbody and contour of the fenders) are usually a major source of corrosion. It is preferable to apply a good quantity of product under these moldings and decorative appliqués. In certain cases, it is even preferable (with the clients permission) to remove and throw out certain moldings such as the ones that outline the fender of certain Japanese models.
  • Treat only metal zones and avoid applying on any plastics or fiberglass

Processing of each part of the Vehicle

Note: Shaded areas of the sketches are generally susceptible to rust.

Hood

Hood

Introduce the 45º flexible rod into all access holes of the outer contour and guide it in all directions in such a way that the entire outline of the hood is saturated with product.

Front Fenders

Front Fenders

Open the front door to have access to the interior surface of the front fender. Use the rigid 48”, 180o jet rod by inserting it to the end and pivoting in such a manner to cover the whole metal surface. Use the flexible 45º tube to treat the inferior part of the fender.

Doors and Sliding Doors

Doors and Sliding Doors

Insert the flexible 45º hose into the flow holes. Coat and saturate all the surfaces of the panels.

IMPORTANT: Be sure to completely saturate the lower corners of the front and rear doors.

Rear Fenders

Rear Fenders

The interior surface of the rear fender is accessible from the inside of the trunk by removing the trim; in certain cases (vans, sport utility), it is easier to remove the rear lights in order to access the zones requiring treatment. In certain vehicles, isolating materials blocks access to the contour of the wheel. If possible, it is strongly advised to remove a small section in such a manner that the product may infiltrate and protect adequately. Use the 48" jet, 360° flexible hose or the 45° hose.

Trunk Lid

Trunk Lid

Insert the 45º flexible hose into all access holes andguide in all directions so that the whole contour of the lid is saturated withproduct.  If a spoiler is installed,ensure the fasteners are treated.

Rocker

Rocker

Most vehicles are equipped with access holes for the rocker; they are found under the vehicle, below the footboards and in a section of the rear wheel. Use the 48" jet, 360° flexible hose.
