Refinishing Wheel Surface
? Remove the damaged wheel from vehicle.
? Clean the damaged area with PrepSol and then sand the scratched or damaged area with Norton 3X Sandpaper (p-graded aluminium oxide grain,) 60, 80 or 100 grit sand paper, sand wet or dry with a wooden sanding block.
? Use a tack rag and wipe the area, using a light pressure
? Fill any minor indentations with Bondo Lightweight Filler 264 and Red Cream Hardener, allowing approx 30 minutes before you shape / sand
? Sand the wheels until you've removed the scratches, `kerbing' marks and/or smoothed the Bondo filler.
? Continue the sanding process using finer and finer grades of UniGrit paper, 220 or 320 grit and finally with 500-grit paper.
? For small hard to reach places use a Dremel Tool and a suitable sanding bit
Note- If the above cleaning method don?t finish to wheels to your liking have them bead blasted
Repainting (cast aluminium )
Wheel Surface
80% of all OEM wheels are finished with a powder coating, as it is the most durable finish you can use.The following will result in a durable re-finished repaint
? Prepare the surface by removing all sandpaper residues with a tack rag, wash surface and then dry thoroughly. .
? Use 3M Painters Masking Tape between the tyre and the wheel rim (or use Vaseline to mask the tyre from paint overspray)
? Wipe-down the wheels with DuPont Prep Sol and allow to air dry.
? Apply a thin coat of 1z 'Haft-Grund' Self-etching Primer to stabilize and provide an etched surface.
? Use at temperatures between 70 ? 90.oF degrees Fahrenheit (.Do not use this paint in damp conditions)
? Shake the can well for at least a full minute
? Push the spray nozzle as you sweep across and release at the end.
? Spray on, spray off. Spray on, spray off; apply as a very fine / thin coat.
? Paint the wheels with two thin coats of silver alloy paint (Wurth German Alloy Silver Wheel) to ensure complete coverage
? Allow air-drying; 1-2 hours between coats and then lightly sand finish, then leave to cure overnight.
? Finish with a clear lacquer paint (Wurth European Blend Lacquers) apply two or three thin coats of clear with about 20-30 minutes of drying time between coats to seal the silver metallic paint and add depth and gloss
? A allow clear coat to air-dry and then cure for 4-6 ours
? Apply a sealant for protection
? If your axle/ wheel centres (hats) are cast iron, you may want to consider painting the hat area with some hi-temp black engine paint
