Maximum Build Primer Filler – Exceptional Filling & Surface Levelling Performance
SUNOX® EXTREME Ultra Build Primer is a premium high-build primer filler aerosol designed for professional automotive refinishing, restoration and repair applications. Developed to provide exceptional filling properties and superior film build, it helps eliminate sanding scratches, minor imperfections and surface irregularities while creating a smooth, uniform foundation for subsequent paint application.
Its advanced ultra-build formulation delivers significantly higher film thickness than conventional aerosol primers, making it ideal for repairs requiring maximum filling performance whilst reducing preparation time and sanding effort.
Fast drying and easy to sand, SUNOX EXTREME Ultra Build Primer offers professional bodyshop-quality results in a convenient aerosol format.
