RUPES Ceramic Denibbing Blade The RUPES Ceramic Denibbing Blade is designed to safely and efficiently remove paint drips, runs, sags, and bonded surface contamination. Made from high-temperature synthesized ceramic, it's built for long-term durability and consistent performance. For standard defects, use the flat side with light pressure to lift above-surface imperfections with minimal risk to surrounding paint. For more severe defects, the chamfered edge with a slightly tilted angle allows for safer, more aggressive removal. Ideal for quickly cleaning up nibs and surface imperfections before polishing.
