Preparation
Proper surface preparation is crucial for optimal adhesion and durability of VHT Engine Enamel.
- Clean the Surface: Thoroughly clean the surface to be painted, removing all dirt, grease, oil, wax, and loose rust. Use a suitable degreaser or wax remover.
- Remove Loose Rust/Paint: Use a wire brush or scuff pad to remove any loose rust or chipping paint. Sand smooth any rough areas.
- Prime (Optional but Recommended): For bare metal or areas with significant surface imperfections, apply a VHT Engine Enamel Primer (e.g., Light Gray Primer) for enhanced adhesion and a smoother finish. Allow primer to dry according to instructions.
- Mask Adjacent Areas: Mask off any areas not intended for painting to prevent overspray.

Application
Apply VHT SP145 Engine Enamel in a well-ventilated area, ideally between 60°F (16°C) and 95°F (35°C).
- Shake Can: Shake the can vigorously for one minute after the mixing ball begins to rattle. Continue to shake occasionally during use.
- Test Spray: Test spray on an inconspicuous area to check color and spray pattern.
- Apply Light Coats: Hold the can 8 to 10 inches (20-25 cm) from the surface. Apply two to three light coats with no more than 10 minutes between coats. Avoid heavy coats to prevent runs and sags.
- Even Motion: Use a steady, sweeping motion, moving the can up and down and side to side to ensure even coverage, especially in hard-to-reach areas.

Curing
Allow adequate time for the paint to dry and cure for optimal performance and durability.
- Dry to Touch: Dries to the touch in 1 hour.
- Handle Time: Can be handled in 2-3 hours.
- Full Cure: Dries thoroughly overnight. For maximum durability and chemical resistance, allow 24 hours for full cure before exposing to extreme conditions or high temperatures.
Troubleshooting Common Issues
If you encounter any issues during application, consider the following:
- Runs or Sags: Caused by applying too much paint in one area or holding the can too close. Apply lighter, more even coats. Allow to dry, then lightly sand and reapply.
- Uneven Coverage: Ensure consistent spray distance and overlapping passes. Proper surface preparation (sanding, priming) also helps achieve a uniform finish.
- Poor Adhesion: Often due to inadequate surface cleaning or preparation. Ensure all contaminants are removed and the surface is properly primed if necessary.
