Aluminun wheel polishing can make cast factory-machine-polished wheels look like new! You'll even be able to get a custom look by painting or powder-coating accent areas prior to a final protectant coating. Using Eastwood's Wheel Smoothing and Buffing Kit, we were able to take an old BMW 325i "bottle cap" wheel from dull to better than new condition. This works with just about any aluminum wheel you choose to polish and buff.
Before starting the stripping process or buffing, be sure to read and adhere to Eastwood's Safety Precautions found in the instruction booklet included with the product; paint strippers are toxic. Also, buffing wheels operate at over 2000 rpm, and could potentially throw off bits of cloth and compound.
It's a good idea to put down a plastic drop cloth and wear chemical-resistant clothing while using the stripper. Be sure to wear rubber gloves and suitable eye protection. You'll also need a plastic paint scraper (a putty knife will do, as will plastic filler spreaders), non-woven abrasive pads, a natural bristle brush, and plenty of clean water.
Completely clean wheel – Use a soap and water solution to remove road tar and contaminants. Eastwood’s PRE (#10041Z) is ideal for removing stubborn road tar.
Fully inspect wheels – Inspect entire wheel for cracks, especially around bead and lug nut areas. If found, seek out a professional to have repairs done or replace wheel.
Remove the old finish – Use Paint Stripper to remove paint, powder coating or clear coats. Brush stripper on in one direction only. Follow instructions on container. Remove coating using either a plastic scraper or a Scuff pad. Reapply stripper to any remaining areas, let sit per instructions, then scrub area with pad to remove coating. Flush wheel with plenty of cold water to remove paint stripper.
Removing minor imperfections – Once your wheels are thoroughly cleaned and inspected, remove minor scratches, nicks or bead damage using files and sandpaper. Blend in with the surrounding area to a 320 grit finish. Do not remove any significant amounts of metal, especially from weld areas on two piece wheels.
NOTE: Use Goblet Buff (#13045) mounted on a buff taper to get into contours and lug nut areas not accessible with 4” buffs. Also use our new Facer Buffs (1”, 2”, 3” diameter; #13171, 13172, 13173) and Mushroom Buff (3” diameter, #13174) to reach very deep recesses and narrow edges. These buffs are “treated” cotton and cut faster than felt bobs when used with Tripoli and Stainless compound. They will also quickly smooth the Greaseless Compound marks. Check our catalog or website for more information.
NOTE: Cleaning the buff frequently using our buff rake (#13120) and reapplying new compound will reduce the chance of adding fine scratches to the wheel. Remember to allow the applied compound to harden.
Since our wheel was originally painted in the deeper nooks and crannies, we want to create the same contrast or drama against the new chrome-like shine of the main surface, fins and rim. We determined we would paint these areas with Eastwood's Silver Argent Rally Wheel Paint. We began masking-off the rim area by applying masking tape over the clean, freshly polished metal. An X-Acto knife was used to trim the tape by simply running around the inner edge of the wheel and peeling away the excess. We covered our main surface area with masking tape as well, trimming away the excess tape with the X-Acto knife.
We were now ready to begin the final finish coating stage. We painted a light but even coat of Eastwood's Self-Etch Primer on the recessed surfaces to assure the paint would bond with the bare metal. After the primer had about 15 minutes to dry, we sprayed the open areas with the Silver Argent wheel paint. The end result was a beautiful chrome-like shine on all of our higher surfaces, offset by the satiny silver rough case areas of the insets.
To keep that mirror shine apply a protective coating of wax, Eastwood’s Diamond Clear for Bare Metal, or better still, powder coat with the Hot Coat (a href="https://www.eastwood.com/paints/hotcoat-powder-coating/powder-coat-guns.html" target="_blank">Powder Coating System. If a painted finish is desired, prime wheel with Eastwood’s Self Etching Primer and then top coat with desired color. If you wish to clear coat a painted wheel for added protection and enhanced looks, we recommend Eastwood’s Diamond Clear for Painted Surfaces.
