Sonus SwirlBuster Polish: Premium Swirl Remover
Sonus SwirlBuster Polish is a premium swirl remover that gently massages the sharp edges of swirl marks while loading the paint with durable, long-lasting acrylic based filling agents. The result is a perfect gloss that lasts with out thinning the paint.
The bottle features 16 oz. of premium swirl busting product.

Like all Sonus products, the directions are clearly labeled on the back.

Copy from back label:
Sonus SwirlBuster Polish is a premium swirl remover polish that gently massages away swirl marks, cobweb effect, and holograms. Special SONACRYLIX additives fill remaining defects and seal your paint with a tough, highly reflective Acrylic coating.
Sonus SwilBuster Polish creates a deep, dark finish that seems to radiate energy. There's nothing else quite like it.
Directions (label copy):
Thoroughly clean and dry your car before polishing. Use Sonus SFX Ultra-Fine Detailing Clay to remove bonded surface contamination. For best results, apply SWIRLBUSTER POLISH by machine using a polishing pad. Apply with a dual-action polisher at high-speed or with a rotary buffer at 1,000 to 1,200 RPM. Apply firm pressure. Work the polish until polish film runs clear and buffs out. Don not buff dry. Buff off polish residue with a microfiber polishing towel or bonnet. Repeat if necessary.
In order to test the effectiveness of the Sonus SwirlBuster polish I prepared the paint according to the directions and taped off a 1 1/2' x 1 1/2' section with 3M Green Painters Tape.

A Brinkmann Swirl Finder light highlighted the condition of the trunk: Surface scouring, water spots, swirl marks, and a rotary haze.

I applied 4 dots of Sonus SwirlBuster Polish a fresh 5.5 inch Lake Country Tangerine pad.


I applied Sonus SwirlBuster Polish with a Porter Cable 7424 XP on speed 5, working in back and forth passes over the working area until the polish became opaque.


After the initial pass over the working area, approximately 15 seconds in.

30 seconds after starting, the polish is beginning to turn clear.

Finally a minute after starting and making approximately 4 passes over the area the polish had turned nearly opaque.

I removed the polish using a Sonus Der Wunder Microfiber Buffing Towel revealing paint that looked significantly darker and reflected light much more evenly.


Two 50/50 shots using just the shop UV light and then the Brinkmann Swirl Finder.


I pulled the M3 into the sun in order to better capture the effect.


The Sonus SwirlBuster Polish created the appearance of swirl free paint while maintaining paint thickness.

Use Sonus SwirlBuster as a non abrasive alternative to polishing paint.
