Swirl marks and holograms are common paint defects caused by improper machine polishing. They reflect light in curved patterns and can ruin an otherwise glossy finish. With the right approach, you can polish safely and achieve a clean, professional-looking surface.
Choose the Right Pad and Polish Combination
Using an aggressive pad with a harsh compound on soft paint often creates micro-scratches that show up as swirls. Match pad softness and polish strength to the paint condition. Start with the least aggressive option that can correct the defects you see.
Work in Small Sections with Controlled Pressure
Large areas invite uneven correction. Polish in small, manageable sections using light to moderate pressure. Let the machine and polish do the work—excessive pressure increases heat and friction, which can cause holograms.
Keep the Pad Clean and Primed
Dirty or clogged pads trap abrasive residue that scratches the clear coat. Clean the pad frequently during the job and lightly prime it with polish before starting each section to ensure smooth, even contact with the paint.
Use Proper Machine Speed and Movement
High speeds and fast, erratic movements are a recipe for holograms. Use moderate speed settings and slow, overlapping passes in a cross-hatch pattern. This keeps correction even and prevents uneven micro-marring.
Finish with a Refining Step
After cutting or polishing, follow up with a softer pad and a fine finishing polish. This refining step removes light haze and machine trails left behind by more aggressive stages, leaving a clearer, deeper gloss.
Inspect Under Different Lighting
Swirl marks can hide under workshop lighting but show up in sunlight or LED inspection lights. Checking your work under multiple light sources helps catch holograms early and correct them before the job is finished.
In conclusion, Avoiding swirl marks and holograms with a buffer machine comes down to controlled technique, clean pads, and the right finishing process. By polishing patiently and refining your final pass, you can achieve a smooth, mirror-like finish without unwanted marks.
