Tie-Coat Primer Quart

The POR-15 Tie-Coat Primer Quart is a professional-grade urethane primer designed for automotive restoration, rust repair, and surface preparation on metal substrates. It is ideal for mechanics and enthusiasts working on bare steel, welded seams, and compromised finishes, bridging the gap between bare metal and topcoat application.

This urethane-based formulation offers exceptional adhesion to bare metal and creates a moisture-resistant barrier that prevents flash rust and oxidation prior to topcoat application. The gray tie-coat finish provides superior color-hiding characteristics and uniform coverage, reducing the number of base and clear coats needed downstream. Urethane primers cure quickly, allowing for faster progression through the finishing schedule.

Mechanics and restoration shops can benefit from the POR-15 tie-coat primer for various applications, including undercarriage repairs and custom fabrication projects where adhesion and corrosion resistance are critical. Its practical 1-quart size ensures targeted applications without waste, delivering professional results at efficient coverage rates.
