LINEAR BLOCKING TOOLS — Precision Sanding for Professional Automotive Finishing
At The Spray Source, we proudly offer a full range of LINEAR BLOCKING TOOLS for professional automotive refinishing. These tools are essential for achieving flawless, straight panels during auto body sanding, ensuring a superior surface ready for paint. Whether you are restoring a classic, completing high-end collision repair, or refining custom bodywork, our collection provides the precision and flexibility required to deliver professional results. Built with attention to detail and tested in real-world environments, every item we carry reflects what professionals actually need in daily use.
What Are LINEAR BLOCKING TOOLS?
They are specialized sanding blocks designed to maintain perfectly flat surfaces during the sanding process. Unlike conventional blocks, these are engineered for maximum surface contact, distributing even pressure along large panels. This is especially critical for straightening doors, hoods, roofs, and quarter panels. The effectiveness of these tools becomes clear when working on irregular surfaces, blending edges, or preparing older panels that have already been through previous work.
The precision of these products for automotive work reduces uneven sanding marks and prevents panel distortion. This makes them indispensable in professional body shops and for serious DIY enthusiasts striving for show-quality finishes.
Why Choose our tools?
Our curated selection of products includes options suitable for every stage of surface preparation. Whether you're working on primer, feather-edging filler, or final wet sanding, these high-precision sanding blocks ensure consistent and accurate results. Designed with durable materials, each tool offers long-term performance in demanding shop environments.
Every product we carry is carefully evaluated by experienced professionals. From build quality to usability, we ensure that every item meets the standards required in real-world collision repair and restoration work. The Spray Source understands that time is money in a busy shop, so we focus on tools that help you work efficiently without sacrificing accuracy.

Flexible Sanding Blocks for Curved and Flat Panels
While sanding blocks are often associated with large, flat surfaces, our collection also includes flexible options. These tools conform to subtle curves, ensuring no area is over-sanded or missed. This versatility makes them ideal for custom work, especially on vehicles with complex contours.
Body lines, door edges, and curved quarter panels require a different approach than flat surfaces. That’s why flexibility matters, particularly when dealing with custom bodywork or vehicles with unique design features. Our selection offers versatility, so you can confidently approach every type of repair or restoration.
Our collection excels in both collision repair and professional car restoration, delivering surface perfection that minimizes rework.

Applications — From Collision Repair to Custom Builds
Whether you're tackling everyday repairs or one-off custom projects, this collection belongs in your sanding arsenal. In collision repair, these blocks help achieve seamless blends where panels have been repaired or replaced. In professional car restoration, they ensure that every surface is straight and ready for show-quality paint.
Inconsistent sanding leads to flaws that only become visible after paint is applied. Investing in the right surface preparation tools helps eliminate these surprises. By using tools designed for precision, your refinishing process becomes more predictable, with fewer re-dos and better customer satisfaction.
Sanding is only one part of surface preparation. We recommend combining these tools with high-quality abrasives, primers, and guide coats from our All Products Collection. This complete system ensures each step builds toward the perfect final finish.
