Aluminum Wheel Recoating Procedure
REMOVAL PROCEDURE1. Remove the tire and wheel assembly.
2. Match mark the tire for reinstallation of the outboard wheel weights after the recoating of the wheel.
3. Remove the outboard wheel weights.
4. Clean the wheel inside and out using a water base all purpose cleaner. Remove grease or oil with a solvent cleaner.
5. Sand over painted areas that do not require recoloring with number 400 grit (wet or dry) in order to promote adhesion of clear coat.
6. For surface damage use the following procedure:
6.1. Mount the tire and wheel on the brake lathe and spin slowly.
Caution: Do not use vehicle power to rotate the wheel while sanding to avoid personal injury.
6.2. Sand the wheel with a backing block or pad.
Notice: Do not use an abrasive coarser than 80 grit or wheel may be damaged.
6.2.1. Hold the abrasive flat to the surface of the wheel.
6.2.2. Slowly move the abrasive back and forth from the center to the outer edge in order to remove damage.
6.3. Use the following sandpaper grits in the order listed:
^ Sand with number 80 grit sandpaper
^ Sand with number 150 grit sandpaper
^ Sand with number 240 grit sandpaper
7. Continue with the Recoating Procedure.
CLEARCOAT DAMAGE ON UNPAINTED WHEELS
1. Apply a chemical stripper.
Caution: Use of rubber gloves and eye protection is necessary to prevent personal injury.
2. Allow the stripper to penetrate coating.
3. Use a small 1/4 inch detail brush dipped in stripper in order to apply material around the perimeter and spoke-like areas.
4. Remove the stripper following the manufacturers recommendations.
5. Sand the wheel with a 240 grit while rotating the wheel on a slow spinning brake lathe or by mounting on vehicle and spinning by hand. This will restore the machined appearance and promote adhesion.
Caution: Do not use vehicle power to rotate the wheel while sanding to avoid personal injury.
6. Continue with the Recoating Procedure.
ALUMINUM WHEEL RECOATING PROCEDURE
1. Clean the surface of contaminants by washing with soap and water.
Caution: Use of rubber gloves and eye protection is necessary to prevent personal injury.
2. Spray the wheel with Amchem number 33 or equivalent.
2.1. Let the wheel soak for 1 to 3 minutes.
2.2. Rinse the wheel with water and blow dry the wheel.
3. Soak the wheel with Amchem #1001 or equivalent.
3.1. Let the wheel soak for 1 to 3 minutes.
3.2. Rinse the wheel with water and blow dry the wheel.
4. Mask off the tire.
5. Finish the wheel with Ditzler Delclear Acrylic Urethane and Ditzler Ultra-Urethane Additive or equivalent using 3 coats. Refer to the labels for specific directions.
^ First Coat - Light mist coat, let flash
^ Second Coat - Light, let flash
^ Third coat - Heavy double wet coat
Caution: To avoid serious personal injury when applying any two part component paint system, follow the specific precautions provided by the paint manufacturer. Failure to follow these precautions may cause lung irritation and allergic respiratory reaction.
6. Let the wheel dry for 24 hours - (or flash for 30 minutes) or force dry at 60°C (140°F) for 30 minutes, then allow to cool for 30 minutes before mounting the tire.
INSTALLATION PROCEDURE
1. Balance the wheel and tire assembly.
2. Replace the original balance weights with nylon coated weights in order to avoid discoloration of the wheel.
3. Install the tire and wheel assembly.
