Machine Polisher & Backing Plate Guide (for Baldwin Park Locals)

A Machine Polisher (sometimes called a 'buffer') is a power tool used for Paint Correction. Use a polisher to apply compounds and polishes, allowing you to remove swirl marks, scratches, and oxidation far more effectively than by hand. This guide explains the two main types—Dual-Action and Rotary—and how to select the correct backing plate for the job.

Dual-Action Polisher vs. Rotary Polisher: Which Do You Need?

Select the right machine polisher for your skill level and paint correction goals.

Dual-Action (DA) Polishers (Beginner-Friendly)

  • What It Is: A Dual-Action (DA) Polisher (or ‘random orbital’) is the safest, most modern tool for paint correction. Its oscillating and free-spinning motion prevents you from “burning” the paint.
  • Attributes: Its “throw” (oscillation size, e.g., 8mm or 15mm) determines its cutting power. DAs are beginner-friendly and create a finish free of holograms (buffer trails).
  • Use This For: Safely removing light-to-medium swirls and applying all-in-one polishes or waxes.

Rotary Polishers (Professional, High-Cut)

  • What It Is: A Rotary Polisher is a direct-drive tool that spins on a single axis. It generates high-heat and cuts fast.
  • Attributes: This is a professional tool for heavy compounding. In untrained hands, its forced rotation can quickly cause holograms or paint damage.
  • Use This For: Removing deep scratches, leveling wet sanding marks, and cutting through heavy oxidation.

A Guide to Backing Plates

The Backing Plate is the polisher accessory that connects the machine to the polishing pad. Match your backing plate to your pad size.

Function (Velcro & Heat Dissipation)

Use the Velcro-hook face to grip your polishing pad. Most modern plates are vented or flexible (made of urethane) to dissipate heat and prevent pad delamination (failure).

Size (3-inch vs. 5-inch)

Use a small (3-inch) backing plate to polish tight areas like A-pillars, mirrors, and bumpers. Use a larger (5-inch or 6-inch) backing plate to correct large, flat panels like hoods, roofs, and doors efficiently.

Let me start off by saying I love all the products they car from Auto Detail to 360! I met Robert back in March when I started working for Wondries! I had used the 360 Brazilian mist before and I never knew he owed the place! I started talking to him more about other products they also carry. I completely switched over from chemical guys to Auto Detail and 360 ! That was the best decision I could have ever Made ! I highly recommend using them VERY FRIENDLY AND FAMILY OWNED BUSINESS !!!!

I loved this place! The girl who helped me behind the counter was very nice and very informative. She helped answer all of my questions. She even recommended a few things. I purchased a 150 gallon water tank and the boss (I assume he was the boss), was very helpful in helping me load it in the truck.
