Key Features:
- Acid-Etch Technology: Chemically bonds to bare metal — no separate metal conditioner required.
- Gray Finish: Neutral tone provides excellent hiding and a consistent base for topcoats.
- Fast Drying: Ready to topcoat in minutes for production-paced body shops.
- Multi-Metal Compatibility: Steel, aluminum, galvanized metal, and other automotive substrates.
