PAIRING BUFFING WHEELS WITH POLISHING COMPOUND CORRECTLY:ALUMINUM METAL POLISHINGPolishing aluminum with our airway buffing wheels are typically done in a two-step process. We recommend pairing our Brown Tripoli Metal Polishing Compound with our orange airway buffing wheels as the first step.For the second step in polishing aluminum, we would want to pair our yellow airway buffing wheel with our Green Rouge Metal Polishing Compound.STAINLESS STEEL METAL POLISHINGPolishing stainless steel with our Airway Buffing Wheels is typically a two step process. The first step is to pair our red airway buffing wheel with out Black Magic Compound. The second step involves using a Pink buffing wheel with our Yellow Deluxe Compound. For an extra show-shine finish, some use a white buffing wheel with our Blue Rouge Metal Polishing Compound at no more than 2,200 RPM.HOW TO POLISH ALUMINUM WHEELS:To polish aluminum and stainless steel wheels, pair the appropriate metal buffing and polishing compound (as listed above) with a smaller diameter airway buffing wheel to get into the hard-to-reach areas of the wheel.PRO TIP: ALWAYS RAKE YOUR BUFFING WHEELS.HOW DO I USE A BUFFING WHEEL RAKE?The buffing wheel should be spinning at it’s normal speed and the rake should be held securely when held up to a stationary bench grinder or lathe. On a grinder, please exercise caution when raking. We recommend using your feet to hold the rake to the ground and holding the angle-grinder to it.WHY SHOULD I RAKE MY BUFF? Raking your buff removes hardened and burned on polishing and buffing compound from the edges of your buffing wheel. Compound build up can reduce the efficiency of the buffing wheel while also creating a rougher surface. If you notice a significant decrease in the residual metal dust produced when buffing, rake the buffing wheel and reapply a small amount of metal polishing compound. we here strive for the best customer service so if any questions just ask.we will ship orders same day if paid before 2:30 central time. have a good day😀
