Rubberized Undercoat

Hi-Tech HT-18023 Premium Rubberized Undercoat is a professional aerosol undercoating designed to protect vehicle underbodies, wheel wells, panels, weld joints, and other exposed metal surfaces from rust, corrosion, moisture, road salt, and debris. Its quick-drying rubberized formula resists cracking and chipping, helps reduce road noise, and dries to a durable black finish that can be painted when desired.

DIRECTIONS:

Make sure the surface is clean, dry, and free of loose rust, dirt, grease, oil, and peeling coatings before application.
Mask surrounding areas that should not be coated.
Shake the Hi-Tech HT-18023 Premium Rubberized Undercoat aerosol can vigorously for at least 1 minute after the mixing ball begins to rattle.
Continue shaking periodically during use.
Hold the can approximately 10–12 inches from the surface.
Apply using smooth, even sweeping motions.
For best results, apply multiple light coats rather than one heavy coat.
Allow adequate drying time between coats.
Once dry, the coating may be painted if desired.
Use only in a well-ventilated area and keep away from heat, sparks, and open flames. Do not store above 120°F (49°C).
