Linear High Build Epoxy Primer Kit – L-411 (Includes Activator – 5 Quarts Sprayable)

Available in Blue, Gray, and Black

Upgrade your bodywork process with the Linear High Build Epoxy Primer Kit (L-411) – the ultimate high-performance, high-build epoxy system from Linear Blocking Tools. Available in three distinct colors—Gray, Black, and the fan-favorite Blue—this 4:1 true epoxy primer delivers unmatched performance with a glossy finish that acts as a built-in guide coat, making it easy to spot waves, low spots, and pinholes with zero added effort.

This is not a hybrid formula—it's a true DTM epoxy primer that adheres directly to bare metal, offering excellent corrosion resistance and rust encapsulation. Designed to streamline your workflow, L-411 allows you to use one bulletproof product from bare metal to topcoat, eliminating the need for multiple primers like spray poly or 2K urethane. The result? Superior uniformity, reduced risk of phantom waves or cracking, and a finish built to last.
