Frequently Asked Questions
What is the difference between a rotary and a dual action (DA) polisher?
A rotary polisher has a direct drive, meaning the pad spins in a single circular motion. This offers maximum cutting power for severe defects but requires significant skill to prevent paint damage and holograms. A dual action (DA) polisher, on the other hand, both spins and oscillates (wobbles) the pad. This random orbital motion is much safer for automotive paint, making it ideal for beginners and most enthusiasts, as it greatly reduces the risk of burning paint or creating swirl marks. DAs are generally slower for heavy correction but safer for finishing.
What orbital throw size should I choose for a dual action polisher?
The orbital throw refers to how far the pad oscillates. Larger throws (15mm or 21mm) cover more surface area per pass, leading to faster paint correction and often a smoother finish, but can be less effective on tight curves and intricate body lines. Smaller throws (8mm or 12mm) offer more control and precision, making them better for contoured surfaces and spot correction, though they may take longer for full panel correction. Your choice should align with the typical size and complexity of the vehicles you detail.
What pads do I need for my power polisher?
Different pads serve different purposes in the detailing process. Cutting pads (often foam or wool, firm density) are used with compounds to remove heavy defects and scratches. Polishing pads (medium density foam) are for lighter defect removal and refining the paint with polishes. Finishing pads (soft density foam) are used for applying waxes, sealants, or glazes to achieve a high-gloss finish. Always match your pad type to the specific product and stage of detailing you are performing.
Can I use a power polisher on all types of car paint?
Power polishers can be used on most automotive clear coats and single-stage paints. However, extreme caution is advised on older, thinner, or repainted surfaces, as these may have less clear coat to work with. Always perform a test spot in an inconspicuous area first to assess the paint’s condition and how it reacts to the polisher and product. Never use a power polisher on matte finishes, as it will alter the appearance and create shine.
How do I prevent swirl marks and holograms when using a power polisher?
To prevent swirl marks and holograms, especially with dual action polishers, proper technique is crucial. Always use clean pads and quality compounds/polishes. Work in small sections, typically 2×2 feet, and apply even, consistent pressure. Keep the pad flat on the surface and use overlapping passes. Ensure you are using the correct speed setting for the product and pad combination. For rotary polishers, avoiding holograms requires advanced technique, including proper pad angle, speed, and finishing down with finer polishes or a DA polisher.
