Professional High Build Primer Filler – Excellent Filling & Sanding Properties
SUNOX® EXTREME High Build Primer is a premium 1K primer filler aerosol designed to provide excellent filling properties, adhesion and sanding performance for automotive refinishing and repair applications. Ideal for use prior to basecoat and topcoat application, it helps create a smooth, uniform surface by filling minor imperfections, sanding scratches and preparation marks.
Its high-build formulation allows greater film thickness than conventional primers, helping reduce preparation time while delivering a professional foundation for painting.
Fast drying and easy to sand, SUNOX EXTREME High Build Primer is suitable for bodyshop repairs, restoration projects, SMART repairs and general refinishing work.
