LeSabre T-Type Wheels



A protective clear or color coating is applied to the surface of original equipment cast aluminum wheels. A surface degradation condition can begin to develop if this clear coating is damaged or removed. This can happen at some automatic car washing facilities using aggressive silicone carbide tipped tire brushes to clean white walls and tires. Once the protective coating is damaged, exposure to caustic cleaners and/or road salt further causes the surface degradation. The following procedure details how to strip, clean and recoat aluminum wheels that are affected by these conditions.

Required Materials:

Amchem Alumi Prep #33 – stock #DX533 or equivalent – cleaning and conditioning chemical for aluminum.

Amchem Aldoine #1001 – Stock #DX50T or equivalent – coating chemical for aluminum.

Ditzler Delclear Acrylic Urethane Clear – Stock #DUA-75 or equivalent.

Ditzler Delthane Ultra-Urethane Additive – stock DXR-80 or equivalent.


Service Procedure:

1.      Mark wheel and wheel stud for position on car.

2.      Remove tire and wheel assembly from car.

3.      Mark location of outboard weights and remove.

4.      Wash wheel inside and out with water base all purpose cleaner. Remove grease and oil with solvent based cleaner.

5.      Mask off tire prior to painting.

6.      Select and follow the correct procedure, “Aluminum Damage on Wheel Surface” or “Clear Coat Damage on Unpainted Wheels”.

7.      Replace wheel weights with nylon coated weights.

8.      Install tire and wheel assembly on car and tighten wheel nuts to proper torque.



Accent Color Preparation

1.      Sand over painted areas that will not require recoloring with 400 grit (wet or dry) to promote adhesion of clear cote.



Aluminum Damage on Wheel Surface

1.      Mount tire and wheel on brake lathe and spin slowly.

2.      Sand wheel with backing block or pad by holding abrasive flat to surface of wheel and moving slowly back and forth from center to outer edge to remove damage. Use the following sandpaper grits in order listed.

A.     Sand with 80 grit.

B.     Sand with 150 grit.

C.     Sand with 240 grit.

3.      Continue with “Recoating Procedure”.



Clear Coat on Unpainted Wheels

1.      Apply chemical stripper. Use ¼” detail brush dipped in stripper to apply material around perimeter and spoke like-areas.

2.      Remove stripper following manufacturer’s recommendations.

3.      Sand wheel with 240 grit while rotating wheel on a slow spinning brake lathe or by mounting on car and spinning by hand. This will restore the machined appearance and promote adhesion.

CAUTION: Do not use engine power to rotate wheel while sanding to avoid serious personal injury.

4.      Continue with “Recoating Procedure”



Recoating Procedure

1.      Clean surface of contaminants.

2.      Soak wheel with Amchem #33 or equivalent from 1 to 3 minutes, then rinse with water and blow dry.

3.      Soak wheel with Amchem #1001 or equivalent from 1 to 3 minutes, then rinse with water and blow dry.

4.      Finish with Ditzler Delclear Acrylic Urethane and Ditzler Ultra-Urathane Additive or equivalent using three coats.

1st Coat – Light mist coat, let flash.

2nd Coat – Light mist coat, let flash.

3rd Coat – Heavy wet coat.


5.      Let dry for 24 hours – (or flash for 30 minutes, force dry at 140 degrees for 30 minutes, and allow to cool for 30 minutes before mounting.
