Preval

<h3>About Preval: Decades of Spray Innovation</h3><p>Founded in 1969 and headquartered in Bridgeview, Illinois, Preval has spent more than five decades earning its reputation as the industry leader in spray and touch-up solutions. What began as a straightforward idea — give hobbyists and professionals alike a portable, refillable way to spray any liquid — has grown into a comprehensive line of spray systems and accessories trusted by everyone from weekend DIYers to automotive body shop technicians.</p><p>Preval's secret is its <strong>patented Venturi Vacuum Process</strong>. Rather than pre-mixing propellant and paint inside a sealed can, the power unit draws liquid up from a separate, refillable glass or plastic reservoir. The propellant and medium only meet at the nozzle, which means the coating exits the sprayer in its true, unadulterated form — no color shift, no contamination. The result is a fine, consistent atomized mist that rivals the output of a full compressor-driven setup, at a fraction of the cost and setup time.</p><h3>Versatility Across Coatings and Industries</h3><p>One of Preval's most compelling traits is how broadly its technology applies. The sprayer handles water-based, latex, oil-based, and solvent-based materials with equal ease. That means a single Preval unit can tackle automotive clear coats, gel coats, rust inhibitors, lacquers, stains, polyurethanes, enamels, primers, and even leather dyes — all without switching equipment. For automotive enthusiasts performing paint touch-ups, panel repairs, or custom refinishing, the convenience of a grab-and-go system that doesn't require a compressor or spray booth setup is genuinely game-changing.</p><p>Preval's <a href="/3225-preval-spray-gun-49300">spray guns</a> are particularly popular in the automotive and marine segments, where precise touch-up work and spot refinishing demand consistent atomization and a controlled fan pattern in tight spaces. The system is equally at home in the workshop, on a job site, or in the field — anywhere a full-size spray rig isn't practical.</p><h3>A Full Ecosystem of Spray Products</h3><p>Beyond the core sprayer, Preval offers a complete ecosystem of complementary accessories. The vGrip Universal Handle converts the power unit into an ergonomic trigger-style spray gun, improving control on larger surfaces. Replacement power units, solvent-proof plastic reservoirs, and glass jars are all available individually, keeping ongoing operating costs low. For those who spray frequently, bundle options like the ValPack bring together multiple power units, an assortment of container sizes, dip tubes, and a vGrip into a single cost-effective kit.</p><p>All Preval sprayer components are designed to be <strong>interchangeable, disposable, and recyclable</strong> — a nod to the brand's commitment to minimizing environmental impact without sacrificing performance. The aluminum aerosol power unit and glass jar are both fully recyclable after use.</p><h3>Who Uses Preval?</h3><p>Preval products are a staple in auto body shops for OEM and commercial-grade paint touch-ups, and they're equally popular among independent restorers and hobbyists who need professional results without a professional spray setup. The barrier to entry is low — no compressor, no airline, no spray booth required — which makes Preval an accessible entry point for anyone learning to spray, while still delivering the fine atomization that experienced painters rely on for blending and feathering work.</p>
