Highlights
- Proprietary 3M™ Trizact™ abrasives start sharp and stay sharp, resulting in more predictable finishes and improved, consistent results
- Ideal for the 3M™ two-step paint defect repair process for high gloss automotive finishes
- Well suited for use on mini random orbital sanders to produce a polish-ready finish
- Produces finer finishes than conventional paper and film-backed abrasives
3M™ Trizact™ Finesse-it™ Film Disc 466LA uses proprietary 3M microreplication technology; micron-graded silicon carbide is formed into tiny pyramids and evenly coated on a non-compressible polyester film backing. Sharp, consistent cutting action makes this abrasive great for final finishing.

3M™ Trizact™ Finesse-it™ Film Disc 466LA features tiny, sharp pyramids that wear gradually during sanding, continually exposing fresh mineral to give you a consistent cut and a predictable, fine finish.
We chose silicon carbide mineral for this abrasive because, while it breaks down faster than aluminum oxide, it tends to produce a brighter finish. It's commonly used for defect removal on clear coats, paint and plastics because it can effectively refine these surfaces without gouging or damaging the workpiece.
The discs are color-coded by grade to reduce the risk for error
3M™ Trizact™ abrasives use 3M microreplication technology, encapsulating mineral inside tiny pyramids. These pyramids are evenly distributed over the backing. While conventionally coated abrasives often have erratically spaced mineral, Trizact™ abrasives focus on uniformity. As pyramids wear, fresh, sharp mineral is exposed to produce a consistent cut and a predictable, fine finish. Altogether, this means fewer scraps and discards as a consequence of inconsistent results. Ongoing sharp cutting action minimizes the need to incorporate other abrasives in the sequence, thereby reducing processing steps and enhancing productivity.
3M™ Trizact™ Finesse-it™ Film Disc 466LA is available in three grades: A3, A5 and A7. The discs are color-coded by grade to reduce the risk for error when there are multiple grades in a sequence. Each disc is designed for quick access and attachment to rotary tools or orbital sanders. Altogether, this disc is a good partner in repairing and finishing workpieces that require a balance between softness and strength — effectively tackling imperfections while maintaining workpiece integrity.
