As the name suggests, the Optimized Surface Preparation targets the entire process and this is a decisive factor. As well as maximizing the performance of every individual phase of the process, each step has also been optimized to work perfectly with all the other steps. Mirka’s OSP abrasives are clearly marked with numbers, making it easy to know which disc or strip should be used 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
Number 4 for finalising the sanding.
