OSP-4 Finishing 4.5″ x 5″ Plain – OS-127-004

The Optimized Surface Preparation system targets the entire process, maximizing the performance of every individual phase. Each step has been optimized to work perfectly with all the other steps. Mirka’s OSP abrasives are clearly marked with numbers telling which disc or strip to use for each step. Number 1 is used for paint removal, number 2 for feather edge, number 3 for preparing the repaired area for primer by reducing scratches and expanding the feather edge, and number 4 for finalizing the sanding.
