● Sanding automotive clear coat, metal surfaces, or composites demands a disc that stays flat, resists tearing, and handles both dry and wet applications. Our GooBetter 6-inch (150mm) polyester film sanding discs feature an industry‑leading 17‑hole dust extraction pattern (small holes 8mm, large holes 10mm) that pulls debris away aggressively, keeping the abrasive clean and your workspace dust‑free. The brown corundum (aluminum oxide) grain is bonded to a high‑strength polyester film substrate – far stronger than paper‑based discs, with excellent flatness, rot resistance, and full waterproof capability. Use dry with a dust‑extracting sander for fast material removal, or wet for a lubricated, haze‑free finish on clear coats and paints. From 60‑grit coarse sanding to 2000‑grit ultra‑fine polishing, these green discs deliver consistent, scratch‑free results. Ideal for automotive paint sanding, metal finishing, woodworking, and composite repair. Upgrade from paper – get longer life, superior flatness, and unmatched dust extraction.

❓ Frequently Asked Questions – 6" 17-Hole Polyester Film Sanding Discs
● Will the 17-hole pattern fit my 6" random orbital sander?
Most 6" random orbital sanders from brands like Mirka, Festool, DeWalt, and Bosch use multi‑hole patterns ranging from 6 to 17 holes. The 17‑hole design provides maximum dust extraction – even if your sander has fewer holes, the disc will still attach securely and offer better dust pickup than a solid or low‑hole‑count disc. For best results, use with a vacuum‑connected sander.
● Why choose polyester film over traditional paper sanding discs?
Polyester film is significantly stronger, more tear‑resistant, and maintains perfect flatness even after prolonged use. Unlike paper, it won't rot or curl when used wet, and it resists humidity in storage. Film also provides a more consistent scratch pattern, reducing the risk of deep gouges and rework. Professionals prefer film for critical automotive and marine finishing.
● Can I use these discs for wet sanding automotive clear coat?
Absolutely. The polyester film is fully waterproof, making these discs ideal for wet sanding clear coat, base coat, and gel coat. Use grits 1000‑2000 with a spray bottle of water. Wet sanding reduces heat (prevents burn‑through), eliminates hazardous dust, and produces a finer, scratch‑free finish. After use, rinse the disc and let dry – it remains ready for the next job.
● How do I choose the right grit for my project?
Use 60‑120 grit for aggressive paint stripping, rust removal, or heavy stock removal on wood. 150‑400 grit for smoothing filler, primer, or deburring metal. 600‑1000 grit for fine finishing before painting. 1200‑2000 grit for wet sanding clear coat to a mirror shine. Always step up gradually and clean or rinse the disc between grits to avoid cross‑contamination.
● Are these discs suitable for metal sanding and rust removal?
Yes. For metal, start with 60‑80 grit to remove heavy rust, scale, or weld spatter. Then 120‑240 grit to smooth the surface, and 320‑600 grit for pre‑paint preparation. The film backing resists tearing on sharp metal edges – a common failure point with paper discs. The 17‑hole pattern also helps evacuate metal dust when used with a dust extractor.
