What is Iridium SR 32mm PSA designed for?
A premium abrasive disc for final-stage sanding in automotive refinishing, collision repair, and transport/vehicle manufacturing.

What advantages does Iridium SR provide?
It delivers uniform scratch patterns that are fast and easy to polish, refined consistency, and durable abrasive life.

Which tools are recommended for use with Iridium SR?
Works best with Mirka cordless sanders—such as the AOS-B and AROS-B series—for precise control during spot repairs and finishing.

Is Iridium SR suitable for wet sanding?
Iridium SR is designed for dry sanding. However, you can use the Mirka Finessing Damper to apply a controlled, minimal amount of liquid. This helps reduce splash and keeps the abrasive clean—but does not make it compatible with traditional wet sanding methods.

Which industries or trades benefit from this product?

• Automotive refinishing (bodyshops, paint correction)
• Collision repair centers
• Vehicle and transport manufacturing (quality control and surface finishing)
• Composite fabricators (e.g., marine or aerospace applications)

How should Iridium SR fit into a finishing workflow?
To get a flawless finish, dry sand, clean the surface, then polish using a water-based compound (e.g., Polarshine or PRO Iridium 1250) and Mirka pads.
