On new and like-new finishes, use SFX-2 twice a year to maintain as-new paint gloss. For a show car finish, follow with SFX-3 for a crystal clear, jewel-like finish. 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 dual-action polisher or a rotary buffer using a Sonus DAS Green Foam Pad or a Sonus SFX-2fp 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 remaining residue with a dry microfiber polishing towel. Repeat until gloss no longer improves. Finish with SFX-3 or wax to lock-in finish.
