Cast aluminum wheels with a clear coat finish that have peeling paint, discoloration of the paint or corrosion should be cleaned and repainted instead of replaced using the following procedure.
360 grit sandpaper.
Nylon auto glass type scraper.
American Sure Seal Silicone Remover (stock number S-STC), 3M number 08984 wax remover or equivalent.*
Paint thinner.
American Sure Seal Wheel Polish - stock DAP or equivalent.*
Enamel color coat paint or lacquer.
American Sure Seal Coricone 1700 Clear Metal Protectant (stock number DCC or equivalent).
DuPont 228S conversion coating or equivalent.
General Purpose Pads, 3M #7448 or equivalent.
American Sure Seal Glaze Cream Cleaner (stock number DGC), 3M number 05979 Clean-N-Glaze or equivalent medium abrasive rubbing compound.*
American Sure Seal Aluminum Cleaner (stock number DWC or equivalent).*
American Sure Seal Paint Remover Product, strip-off (stock number SSO or equivalent).*
1. Remove wheel and tire assembly from car. Remove tire from wheel (after marking wheel/tire relationship) or mask off tire prior to painting. If wheel and tire are not separated, mark weights and remove.
2. Using a general purpose pad or buffing wheel and the Clean-N-Glaze, aggressively rub over the machined surface to remove some of the corrosion and restore most of the lustre.
3. Wipe over the previously cleaned surfaces with an aluminum cleaner-polish to obtain maximum lustre.
4. Using the silicone remover, clean the entire wheel. Wash off with clear water and air blow dry.
USE OF RUBBER GLOVES AND EYE GOGGLES IS NECESSARY TO PREVENT PERSONAL INJURY.
5. Using the paint stripper, spray the entire wheel surface with this product. Wait two (2) or three (3) minutes and then remove with a high pressure water hose.
Steps 6 through 12 are to be used only on aluminum wheels with painted surfaces. Painted aluminum wheels began to be installed in 1980.
6. If peeling or discoloration is extremely bad, it may be necessary to use the paint stripper. Scrape off any loose paint with a nylon scraper and/or 360 grit sandpaper.
7. Wipe entire wheel clean with the silicone remover and flush off again with water, followed by blow drying.
8. Mask off areas of wheel not to be painted.
9. Wipe over the painted surface with the aluminum cleaner; then apply the metal prep., following label directions. (This is a two-step operation which will improve the adhesion of the primer.)
10. To ensure coverage in all areas, an application of zinc chromate primer should be applied to the wheel painted surface in four (4) light applications, rotating the wheel 900 between applications.
11. Apply the color coat using the same procedure as for the primer.
12. After ten (10) minutes of air drying, heat may be applied to the paint to reduce drying time.
13. When the wheel is completely dry, remove masking tape. Wheel must be perfectly clean of foreign material and dry before applying Coricone 1700, and clean the masked area with wax or silicone remover to eliminate tape residue.
14. Spray two (2) light coatings of Coricone 1700 wheel protector on wheel allowing two (2) or three (3) minutes between coats. The clear coat will put an invisible coating on top of the painted surface and the polished aluminum.
15. DO NOT use heat on clear coat, allow to air dry for 24 hours.
16. Reinstall the tire and wheel (re-align the index marks and/or the balance weight).

Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
