FAQs
What is the Polarstar SR 32mm Channel PSA disc used for?
Polarstar SR is designed specifically for precision spot repair in automotive environments, particularly for removing dust nibs and correcting small defects in clear coats and top coats.
Is this abrasive suitable for wet sanding?
Yes. Polarstar SR is optimized for wet sanding, providing smoother results and better control while minimizing airborne dust.
Does the film backing make a difference?
Yes. The durable film backing ensures the disc holds up during use, resists tearing, and delivers consistent, smooth sanding results.
What does PSA mean?
PSA stands for Pressure Sensitive Adhesive.
It means the back of the disc is coated with a sticky adhesive that allows it to easily stick to a sanding tool or backup pad — no hook & loop (Velcro) or clamps needed. They're perfect for spot repairs and situations where you need precision and consistency — exactly what Polarstar SR is designed for.
