The heat treatment hardens the grain, making it last longer on hard materials like metal and auto filler. Electrostatic orientation ensures every grain stands upright for a consistent cut, so you don't get uneven scratches or bald spots. Combined with the anti‑clog coating, these discs outperform standard brown aluminum oxide discs by a noticeable margin.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-item\"\u003e\n\u003cdiv class=\"nca5-faq-question\"\u003e🧰 What grit should I use for auto body filler vs. final paint prep?\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-answer\"\u003eFor shaping body filler (bondo), start with 80‑120 grit to remove excess filler quickly. For smoothing the filler before primer, use 150‑180 grit. For final scuffing of primer before paint, 220‑240 grit is ideal. Always progress through grits in steps to eliminate deep scratches. Our 80-240 set covers the entire auto body prep sequence.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-item\"\u003e\n\u003cdiv class=\"nca5-faq-question\"\u003e🔘 Can I use these discs on hardwoods like oak or maple?\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-answer\"\u003eAbsolutely. The heat‑treated aluminum oxide cuts hardwoods efficiently without premature dulling. The anti‑clog coating prevents resin from building up on the disc when sanding oily or resinous woods. For best results on hardwoods, use 80‑120 for stock removal, 150‑180 for smoothing, and 220‑240 for final sanding before finish application.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-item\"\u003e\n\u003cdiv class=\"nca5-faq-question\"\u003e🧲 How long do these discs typically last compared to cheap discs?\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-answer\"\u003eUnder normal use with light to medium pressure, an 80‑grit NCA disc can last 2‑3 times longer than a standard economy disc. Users report sanding 25‑35 sq. ft. of auto primer or 20‑25 sq. ft. of hardwood per disc. The anti‑clog coating is the key – it keeps the abrasive surface open so you're not wasting time with a clogged disc.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"nca5-faq-item\"\u003e\n\u003cdiv class=\"nca5-faq-question\"\u003e🔘 Do you offer higher grits beyond 240?
