Body and Frame Undercoating

Body And Frame Undercoating

1. WARNING:
- Always refer to Material Safety Data Sheet (MSDS) when handling chemicals and wear protective equipment as directed. Examples may include but are not limited to respirators and chemically resistant gloves. Failure to follow these instructions may result in serious personal injury.
- Always wear protective equipment including eye protection with side shields, and a dust mask when sanding or grinding. Failure to follow these instructions may result in serious personal injury.

NOTICE: Do not allow undercoating on powertrain components. Failure to follow these instructions may result in incorrect operation of these components.

NOTE:
- Refer to product label for preparation and handling instructions.
- Avoid high-pressure water spray cleaning to treated underbody area for 24 hours.

Wire brush the area and make sure the surfaces are free of oil, dirt and other foreign material. Carry out the undercoating process in the following sequence.

1 Thoroughly clean and degrease metal surfaces using metal surface prep to remove wax and grease.
2 For best results, the vehicle should be at room temperature.
- Canister attaches directly to the dispensing gun. Attach the undercoating canister to the Undercoating Spray Gun 286-00001.

3 Undercoat should be applied after the welding and refinishing process. Product cannot be welded through.
4 Air pressure setting for applicator gun is 552-621 kPa (80-90 psi).
- Apply light mist coats, applicator sprays in fogging pattern.
- Material displaces moisture.

5 Clean up any overspray with a mild solvent such as mineral spirits or bug and tar remover.

NOTE: The following illustrations provide typical applications to frame rails and are not vehicle specific.

2. NOTE: Frame rail exterior spot-weld flange view.

Apply undercoat material to the exterior exposed edges after carrying out the welding and refinishing process.







3. NOTE: Cross section view of typical unibody frame rail shown.

Apply rust inhibitor to the inner surfaces of the rail after carrying out welding process. Use the long wand and insert as far as possible, depress trigger and wait 2-3 seconds and slowly pull the wand to make sure the area is completely fogged.







4. NOTE: Full frame vehicle, front rail-to-mid rail section repair shown.

Apply undercoat material to the exposed surfaces after carrying out the welding process. Make sure to completely cover any bare metal areas.
