Overview
Built for the job.
Dynatron™ Yellow Spreader helps smooth body fillers, putties and glazes being used in automotive restoration projects. The spreader smooth out auto body restoration products so they are perfectly flush with the surrounding edges of the repair area.
The Dynatron 344 Spreader is a 3-in × 4-in hand-held applicator designed for precise distribution of primers, sealers, and low-viscosity coatings in collision repair and refinishing operations. Its lightweight yellow body provides clear visibility on the work surface and ergonomic handling for repetitive use.
Engineered for a broad range of substrates, the spreader performs reliably on aluminum, steel, galvanized metal, wood, fiberglass, polyester, SMC, concrete, e-coat, and primer films. The tool's flat, rigid blade ensures uniform coverage with minimal flash time, reducing rework and material waste across diverse repair applications.
When using the Dynatron 344 Spreader, technicians should wear appropriate personal protective equipment-including chemical-resistant gloves, safety glasses, and a particulate respirator if aerosolized materials are present. Operate in a well-ventilated area to maintain safe exposure levels to volatile compounds.
