This complete system includes 1 gallon of gray urethane primer surfacer and 1 quart of urethane hardener, delivering a 4:1 mix ratio to produce 1.25 gallons of sprayable two-component (2K) primer—ready to handle demanding automotive refinishing projects. Engineered with a high-solids, high-build formula, this primer provides exceptional filling capabilities, making it ideal for leveling medium to deep sand scratches while creating a smooth, uniform surface for topcoats. The advanced formulation ensures excellent color holdout under all urethane finishes, helping your final paint achieve maximum depth and accuracy without shrinkage. The DTM4200 direct-to-metal capability allows for strong adhesion across multiple surfaces, including properly prepared bare metal, previously painted surfaces, body filler, and most automotive plastics. Its fast-drying performance and easy sanding (wet or dry without clogging) streamline your workflow, reducing prep time and improving efficiency. For added versatility, the primer can be tinted using primer tints or basecoat toners to match your specific project needs. Manufactured in the USA, Restoration Shop coatings are built with premium-quality ingredients to ensure reliable, consistent performance. Whether you're restoring a vehicle or completing a custom paint job, this primer system delivers the durability, adhesion, and finish quality professionals demand.
