The disc uses a ceramic and aluminum oxide mineral blend to maintain consistent cut rate and surface finish throughout the disc life. At 5 inches in diameter and 800 grit, it targets fine sanding stages where surface refinement and finish quality matter. A multi-hole pattern supports dust extraction and reduces loading, keeping the cutting surface clear longer. An anti-loading coating and upgraded resin system add durability. Automotive body technicians and paint prep professionals are the primary installers of this product.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for residential and commercial automotive refinishing environments, including body shops and detail prep facilities. The 800 grit rating positions it for final-stage paint prep, scuff sanding, and finish leveling on painted panels and body substrates. The Hookita hook-and-loop style attachment allows fast disc swaps on compatible backup pads, reducing downtime during multi-stage sanding workflows. The multi-hole pattern aligns with most standard backup pads to maintain dust extraction performance across the repair process.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic and aluminum oxide mineral blend for consistent cut and finish at 800 grit\u003c\/li\u003e\n  \u003cli\u003e5 inch diameter with multi-hole pattern for dust extraction and reduced loading\u003c\/li\u003e\n  \u003cli\u003eAnti-loading coating keeps the cutting surface clear of dust and debris\u003c\/li\u003e\n  \u003cli\u003eHookita hook-and-loop attachment for fast disc changes on compatible backup pads\u003c\/li\u003e\n  \u003cli\u003eUpgraded resin system improves disc durability and extends usable life\u003c\/li\u003e\n  \u003cli\u003eSuited for final-stage paint prep, scuff sanding, and finish leveling\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Hookita-compatible backup pads; the multi-hole pattern aligns with most standard 5 inch backup pads used in automotive paint prep and body repair applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis disc is installed and used by automotive body technicians and paint prep professionals.
