Nylon Cup Brushes for Spray-In Bedliner Preparation

Precision Surface Prep for Custom Truck Bedliners

Achieve flawless results in your vehicle customization projects with Scorpion’s 4" and 6" Nylon Cup Brushes. Engineered specifically for spray-in bedliner preparation, these brushes deliver consistent surface profiling to ensure maximum coating adhesion and long-lasting performance.

Whether you're working on truck beds, rocker panels, or off-road builds, proper prep is critical—and these tools are built to make it faster, safer, and more efficient.

Designed for Control, Durability, and Professional Results

Unlike standard abrasive tools, these nylon cup brushes feature angled bristles that easily reach into truck bed ribs and contours. This design reduces the risk of over-sanding while maintaining even pressure across surfaces.

Optimized for use with a standard buffer or polisher at 1000–1400 RPM, they provide the control needed for professional-grade finishes without damaging the substrate.

Product Description 

Looking for the best tool for truck bedliner surface preparation? Scorpion Nylon Cup Brushes are a must-have for spray-on bedliner installers who demand efficiency and precision.

Available in both 4-inch and 6-inch sizes, these brushes are ideal for prepping surfaces prior to applying custom truck bedliner coatings. The flexible nylon bristles remove contaminants and create the perfect profile for coating adhesion—without the aggressive cutting action that can lead to costly mistakes.
