When selecting Lude Polish, you must prioritize chemical composition and abrasive grit size. For high-gloss finishes, look for formulations with nano-silica or high-grade carnauba wax content. Ensure the pH level is neutral (7.0 ± 0.5) to prevent corrosion on sensitive surfaces. Additionally, verify the viscosity to ensure compatibility with your application method, whether it be manual buffing or high-speed rotary machines. For industrial safety, the flash point should be >60°C to minimize fire risks during storage.
