What It Is
A waterborne enamel formulated to go directly onto properly prepared metal — primer and finish thinking in one system — with corrosion resistance and color retention engineered for exterior metal that flexes and weathers.
How Our Crews Use It
Steel garage doors are its home field: panel seams flex constantly and shed brittle finishes, so we want an enamel made for metal movement. Also our pick for metal railings and utility doors.
Key Benefits
- Direct-to-metal — self-priming on properly prepped metal
- Rust inhibition in both primer and finish coats
- Excellent gloss and color retention
- Fast dry and recoat
- Waterborne — no fire hazard
