Mirka Iridium Soft 3in Grip Multifit P400 Sanding Discs - 20/Box

Mirka Iridium Soft 3 inch Grip Multifit P400 sanding discs are soft foam abrasives designed for dust-free dry sanding in automotive OEM and collision repair applications. They are ideal for fine surface preparation, smoothing primer, and refining surfaces before progressing to higher finishing grits.

Built with a three-part construction, Iridium Soft combines durable aluminum oxide abrasive grains with a flexible foam backing and a secure Grip attachment layer. This structure allows the disc to conform to curves and complex surfaces while maintaining even pressure and a consistent finish. The Multifit hole pattern improves dust extraction efficiency, helping reduce clogging, pilling, and swirl marks for cleaner sanding and improved surface quality.
