More about Sonus SFX Foam Pads...
Sonus SFX 6” polishing pads are precision made for use with dual-action polishers or rotary buffer. Sonus SFX pads feature engineered prepolymer foams that are hydrophilic, meaning they quickly absorb polish and swell. The prepolymer foam offers superior durability and generates just the right amount of work (heat) to offer great polishing action, even with a dual-action machine.

The hydrophilic nature of the SFX pads improves polish “hang time”, which is the amount of buffing you can perform before your polish dries out, forcing you to stop and apply more polish. The benefit is an even and complete break down of the polishing oxides for a perfectly clear final finish.

Unlike most foam pads, which have their Velcro backing applied after the foam disk is cut, the Velcro backing is applied to the SFX foam in its sheet form during the foam manufacturing process. The lamination process creates a complete bond between the Velcro and foam that will not delaminate under the extreme stress of a high performance dual-action polisher.

Sonus SFX pads are very dense. They have a small, uniform cell structure that efficiently transmits energy to the polish, allowing it create a finer paint finish. Even the SFX-3 Final Finish pad is dense, whereas most final finish pads are soft and spongy. The density allows pressure to be applied to the pad, without forcing out all of the polish, for a superior final finish.

NOTE: Sonus SFX pads must be use in conjunction with a Velcro backing plate from 4.75" to 5". For improved polishing safety, a flexible backing plate is recommended.

We recommend washing your foam buffing pads by hand in cool to lukewarm water with the Sonus Der Wunder Wasche. If they are super dirty you can soak them for 10 minutes then rinse until water runs clear. Squeeze out the excess water and allow to air dry on a plastic drying rack with the Velcro side up so water is not draining and sitting in the Velcro backing. Don’t worry if they don’t look new when you are finished, some staining and wear is normal.
