The HI-TECH 18023 Premium Rubberized Undercoat is a high-performance aerosol solution designed for vehicle protection. This formula provides rust prevention, moisture protection, and sound dampening. It applies easily, drying to a deep black, rubberized finish that resists road salt, gravel, water, and corrosion. It is suitable for undercarriages, fender wells, and rocker panels, and helps reduce road noise. Once cured, the undercoat is paintable and is VOC-compliant, making it suitable for professional and DIY automotive applications on cars, trucks, and RVs.

Einrichtung und Vorbereitung
- Sicherheit geht vor: Work in a well-ventilated area. Wear appropriate personal protective equipment, including gloves, eye protection, and a respirator.
- Oberflächenreinigung: Ensure the application surface is clean, dry, and free of loose rust, dirt, grease, oil, and old flaking undercoating. Use a degreaser if necessary, and allow the surface to dry completely.
- Maskierung: Mask off any areas not intended for coating, such as exhaust systems, brake lines, and painted body panels, to prevent overspray.
- Temperatur: For best results, apply when ambient temperature is between 50°F (10°C) and 90°F (32°C).
- Dose schütteln: Shake the aerosol can vigorously for at least one minute after the mixing ball begins to rattle. Continue to shake occasionally during application.
Bedienungsanleitung (Anwendung)
- Testspray: Before applying to the vehicle, test spray on a scrap piece of material to ensure proper spray pattern and consistency.
- Anwendungsdistanz: Hold the can 10-12 inches (25-30 cm) from the surface.
- Even Coats: Apply in smooth, even strokes, overlapping each pass slightly. Avoid heavy, thick coats to prevent sagging and ensure proper drying.
- Mehrere Schichten: For enhanced protection and sound dampening, apply multiple thin coats. Allow 15-30 minutes between coats for flash-off.
- Trocknungszeit: The undercoat is typically tack-free in 1 hour and fully cured in 24 hours, depending on temperature and humidity. Do not expose to moisture or road debris until fully cured.
- Lackierbar: Once fully cured (after 24 hours), the undercoat can be painted over if desired.
Wartung
- Regelmäßige Inspektion: Periodically inspect the undercoated areas for any signs of damage, chipping, or wear, especially after driving in harsh conditions (e.g., salted roads, gravel).
- Reinigung: Clean the undercoated surfaces with mild soap and water. Avoid harsh chemicals or high-pressure washing directly on the undercoat, as this may compromise its integrity over time.
- Touch-Ups: If minor damage or wear is observed, clean the affected area thoroughly and reapply a thin coat of HI-TECH Premium Rubberized Undercoat to maintain protection.
- Lagerung: Store the aerosol can in a cool, dry place, away from direct sunlight and heat sources. Ensure the cap is securely replaced after use.
Fehlerbehebung
- Problem: Uneven spray or product coming out in chunks.
- Lösung: This often indicates insufficient shaking or a clogged nozzle. Ensure the can is shaken vigorously for at least one minute before use and periodically during application. If the nozzle is clogged, remove it and clean it with mineral spirits or a thin wire. Replace the nozzle if cleaning is ineffective. Ensure ambient temperature is within the recommended range (50°F - 90°F).
- Problem: Poor adhesion or peeling.
- Lösung: Poor adhesion is typically due to inadequate surface preparation. Ensure the surface is completely clean, dry, and free of all contaminants (grease, oil, loose rust, dirt) before application. Sanding lightly may improve adhesion on very smooth surfaces. Avoid applying in high humidity or cold temperatures.
- Problem: Sagging or dripping.
- Lösung: This occurs when too much product is applied in a single coat. Apply multiple thin, even coats instead of one heavy coat. Allow adequate flash-off time (15-30 minutes) between coats.
- Problem: Slow drying time.
- Lösung: Drying time can be affected by temperature, humidity, and coat thickness. Ensure application is done in a well-ventilated area within the recommended temperature range. Avoid applying in high humidity. Apply thinner coats to facilitate faster drying.
