3D ACA 520 Finishing Polish is a professional-grade fine finishing polish engineered to remove light paint defects, compounding haze, swirl marks, and holograms while producing exceptional clarity and gloss. Powered by 3D’s proprietary Alpha Ceramic Alumina abrasive technology, ACA 520 is the ideal final refinement step after heavy correction or as a standalone polish on paint that only requires light defect removal.
Key Features & Benefits
🔹 Professional Finishing Polish – Refines paint after compounding to remove residual haze, holograms, light swirls, and fine imperfections while maximizing clarity and gloss.
🔹 Alpha Ceramic Alumina Technology – 3D’s proprietary ACA abrasive technology uses ultra-fine abrasives to efficiently refine the surface without unnecessarily aggressive cutting.
🔹 Hologram-Free Finish – Designed specifically to eliminate holograms and rotary polishing trails, leaving behind a clean, glass-like final finish.
🔹 Ideal Second Step After Compounding – The natural follow-up to 3D ACA 500 or ACA 510 when performing a professional two-step paint correction.
🔹 Excellent on Dark & Sensitive Paint – Ultra-fine abrasives and a filler-free formula make ACA 520 particularly effective when maximum clarity is required on black, dark-colored, or sensitive finishes.
🔹 True Paint Correction Without Fillers – Rather than temporarily concealing defects, ACA 520 mechanically refines the surface so your finished results remain visible after wipe-down and inspection.
🔹 Superior High-Gloss Finish – Enhances paint depth, reflectivity, and clarity to produce the crisp final finish expected from professional paint correction.
How to Use
Step 1: Wash, dry, and thoroughly decontaminate the vehicle before polishing. If heavy defects are present, complete the necessary compounding steps first.
Step 2: Attach a clean foam polishing or finishing pad to your polisher.
Step 3: Apply a few small drops of ACA 520 evenly across the pad.
Step 4: Spread the polish across a manageable working section before beginning your polishing passes.
Step 5: Work the product using slow, controlled, overlapping passes until haze, holograms, and fine defects have been removed.
Step 6: Wipe the section clean with a fresh microfiber towel.
Step 7: Inspect the paint under a high-quality LED inspection light from multiple angles to confirm that the defects have been fully removed.
Pro Tip: When ACA 520 is your final polishing step, resist the temptation to use an unnecessarily aggressive pad. A quality foam polishing or finishing pad allows the ultra-fine ACA abrasives to maximize clarity and gloss while minimizing the possibility of introducing new haze into sensitive paint.
Why We Love It
ACA 520 is great because the final polishing step is where a good paint correction becomes a great one. ACA 500 can handle the serious defects, but ACA 520 is what brings back the clarity, depth, and crisp reflection you want before applying protection. It works especially well on dark and sensitive paints where even minor haze or holograms can ruin an otherwise excellent correction. The filler-free formula also means the finish you see under your inspection light is the finish you actually created
Compatible With / Works Best With
✅ 3D ACA 500 X-Tra Cut Compound – Use ACA 500 for heavy defect removal, then follow with ACA 520 to refine compounding haze and maximize final clarity and gloss.
✅ Foam Polishing & Finishing Pads – Pair ACA 520 with an appropriate foam pad to remove light defects and achieve a clean, hologram-free finish.
✅ Ceramic Coatings, Waxes & Paint Sealants – Use ACA 520 as the final corrective polishing step before properly preparing the paint and applying your preferred protection.
Frequently Asked Questions
❓ What is 3D ACA 520 designed to correct?
💡 ACA 520 is designed for final paint refinement, including holograms, light swirl marks, fine scratches, surface haze, and imperfections remaining after a compounding step.
❓ Should I use ACA 500 or ACA 520?
💡 Use ACA 500 when you need aggressive correction for heavier scratches, oxidation, swirls, and substantial defects. Use ACA 520 for light correction and final refinement. On heavily damaged paint, the two work together as a compound-and-finish system: ACA 500 for the initial cut followed by ACA 520 for final clarity and gloss.
❓ Can ACA 520 be used by itself?
💡 Yes. If the paint only has light swirl marks, wash-induced scratches, haze, or minor imperfections, ACA 520 can be used as a standalone polishing step without compounding first.
❓ Will ACA 520 hide scratches with fillers?
💡 No. ACA 520 is a filler-free finishing polish designed to actually refine paint defects rather than temporarily conceal them.
❓ Is ACA 520 good for black paint?
💡 Yes. ACA 520 is especially useful on black, dark-colored, and sensitive finishes where holograms, haze, and fine polishing defects are particularly easy to see.
❓ Do I need to use ACA 520 after ACA 500?
💡 Not every paint system will require the same process, but ACA 520 is specifically designed as the natural finishing step after ACA 500 or ACA 510 when compounding leaves haze, holograms, or other fine defects behind.
❓ Can I apply a ceramic coating after ACA 520?
💡 Yes. ACA 520 is an excellent final polishing step before a ceramic coating. After polishing, thoroughly prepare the surface using the coating manufacturer’s recommended panel prep to remove polishing residue before applying the coating.
❓ Is ACA 520 body shop safe?
💡 Yes. ACA 520 is silicone-free, water-based, filler-free, and specifically formulated for use in professional body shop and refinishing environments.
