Feature details
Product Features
48-Hole High-Efficiency Dust Extraction Pattern
Engineered with an optimized 48-hole vacuum pattern to maximize dust extraction efficiency during body filler and primer sanding. Prevents dust clogging and grain loading for cleaner, dust-free sanding operation.
Ceramic & Zirconia Blend Abrasives
Delivers stronger cutting performance with up to 2× faster stock removal than conventional abrasives, while providing extended service life.
Polyester Film Backing
Constructed with a high-strength polyester film backing that offers superior flatness and durability compared with traditional paper backing. Excellent tear resistance makes it suitable for both dry and wet sanding applications.
Anti-Loading Coating
Helps minimize dust accumulation and extends effective sanding life, especially for body filler and primer surfacer sanding applications.
Electrostatic Grain Distribution
Manufactured using electrostatic coating technology to ensure a more uniform and sharper abrasive grain orientation, improving cutting consistency and surface finish quality.
Hook & Loop Design
Provides secure attachment for stable operation while allowing quick installation and replacement, making it ideal for continuous sanding processes.
Wide Range of Applications
Suitable not only for automotive refinishing but also for metalworking, woodworking, stone processing, and electronics (3C) surface finishing applications.

Common questions
FAQ
Why are film abrasives more stable and less likely to shed grit or deform in continuous sanding?
Why is film abrasive more stable and less likely to shed grit or deform?
You may also want to compare this with Why can film sanding discs still leave deep scratches or random swirl marks? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
In continuous sanding, the main reasons are:
Higher dimensional stability
Film backing is less likely to curl or deform under heat and pressure changes, keeping contact more uniform.
More even pressure transfer and scratch pattern
A stable backing helps reduce random deep scratches and improves finishing consistency before polishing.
Better grit retention in high-frequency work
Film products often maintain cutting performance longer, reducing frequent disc changes.
Stronger anti-clogging performance with dust extraction
With proper suction and pressure control, film abrasives can deliver more stable durability and process consistency.

What abrasive grit sequence is more reliable for automotive refinishing?
There is no single fixed sanding sequence for every repair job, but a safe rule is to move from coarse to fine in gradual steps.
You may also want to compare this with In automotive refinishing, how should you choose between dry sanding and wet sanding? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
A common workflow is:
-
P80-P120: for initial body filler shaping, correcting obvious defects, or removing old coatings quickly.
-
P150-P240: for intermediate sanding to remove deeper scratches left by the previous step.
-
P320-P500: for surface preparation before primer or surfacer.
-
P800-P1500: for fine sanding before topcoat, blending areas, or higher-finish refinement.
-
Above P1500: better suited to fine wet sanding, pre-polish preparation, or correcting minor defects on high-gloss surfaces.
Practical tip:
Avoid jumping directly from a very coarse grit to a very fine grit. Deep scratches from the previous step can remain and cause rework. A step-by-step progression is usually more stable.

In automotive refinishing, how should you choose between dry sanding and wet sanding?
Both dry sanding and wet sanding are common. The key is not which one sounds more advanced, but which one suits the current step better.
You may also want to compare this with What abrasive grit sequence is more reliable for automotive refinishing? and Why do abrasives clog, run hot, or shed grit, and how can you reduce these problems?.
In general:
-
Dry sanding is better for fast shaping, higher efficiency, and continuous work with a dust extraction system.
-
Wet sanding is better for fine surface refinement, controlling local heat buildup, and reducing airborne fine dust.
When to prioritize dry sanding:
Dry sanding is usually more efficient for body filler shaping, sanding surfacer or primer, and any step where material must be removed quickly.
When to prioritize wet sanding:
Wet sanding is usually better for pre-topcoat refinement, pre-polish correction, and jobs where scratch consistency matters more.
Practical note:
Before wet sanding, confirm that the abrasive and backing support wet use. During dry sanding, poor dust extraction will make clogging, heat, and dust problems more obvious.
