Direct-to-Metal (DTM) Rust Preventive Top Coat
POR‑15 Top Coat is a high‑performance direct‑to‑metal coating designed to protect surfaces that are vulnerable to corrosion. Formulated for exceptional durability, it delivers long-term gloss, excellent colour retention, and outstanding weather resistance—even under harsh UV exposure.
This top coat can be applied directly to metal without the need for a primer or undercoat. When used over POR‑15 Rust Preventive Coating, the two products create a permanent, long-lasting barrier against rust and moisture.
It will not crack, chip, or peel—and provides a professional, long-lasting finish every time.
