Restores damaged, oxidized and abused paint! Removes paint scratches and heavy swirl marks.When the appearance of your paint deteriorates from exposure or damage, you need a polish that will quickly, yet gently, remove the damaged paint to reveal a fresh, brilliant finish. This is exactly why we created Sonus Restore (SFX-1). Sonus SFX-1 is a cutting polish designed to remove heavy oxidation caused by exposure to the elements (sun and weather) and finish marring created by chemical fallout, hard water etching, contact scuffing, surface scratches or the ravages of poor detailing tools. Repairs surface scratches Removes heavy swirl marks and oxidation Clearcoat safe! Sonus SFX-1 is a fast-action cutting and paintwork restoration polish. Use SFX-1 to cut and buff 1200 grit sanding marks, heavy swirl marks, surface scratches, orange peel and severe oxidation. You may also use Sonus SFX-1 to repair the damage cause by water spot etching and bird droppings. Sonus SFX-1 is a machine polish. It requires enough “pad energy” to break down its polishing oxides so that it can polish out and leave a clear finish. Sonus SFX-1 may be used by hand as an isolated scratch remover. When used by hand, it must be used in conjunction with the Sonus SFX Pro-Applicator. Sonus SFX-1 is a silicone-free, body shop safe formula. When finished polishing, what you see is what you get. SFX-1 does not contain fillers or waxes that mask or hide imperfections. Directions:Use by hand or machine in conjunction with proper applicator pads only. Do not use in direct sunlight. Shake well before use. For best results, apply with a Porter Cable 7424 XP dual-action polisher or a rotary buffer using a Sonus DAS Orange Foam Pad or a Sonus SFX-1fp Foam Pad. By hand, use a Sonus SFX-Pro Applicator. Use in a ventilated area. Do not use in direct sunlight. By dual-action polisher, apply at ½- to ¾-speed with moderate pad pressure as necessary to achieve results. By rotary buffer, apply at 700-1,000 RPM. Reduce pressure and increase speed as the polish dries. Buff to a haze and wipe off residue with a dry microfiber polishing towel. Repeat until the damage or flaw is removed. Follow with Sonus SFX-2 to restore full gloss.
