Circular buffer compounding pad as recommended in Nuvite Detailed Metal Polishing Procedures. A Compounding Pad with 7” diameter with 1” to 1 1/4″ tufted wool face pyle and hook & loop drive backing should be used. Works great with Nuvite #EQ-136 Rotary buffer, or most other popular brands of circular buffers. Use with Nuvite NuShine II compounding grades F7 & F9, G6, or C to“heal” the aluminum surface. This preps the surface to make it ready to take “The Nuvite Look” final step with a Random Orbital buffer and NuShine II grade S. Buy several, as we recommend changing pads each time you change grades for best results. Read the link for cleaning procedures below.
