Yes — DiamondFinish Clear can be applied directly over rusted metal to lock in that vintage patina and stop rust from spreading further.
💡 Pro Tip — Want a Matte Finish? Lightly sand the final coat with steel wool 24 hours after application to knock down the gloss and achieve a natural matte look. |
How to Apply DiamondFinish Clear Over Rust
Step 1 — Clean the Surface
Mix a solution of 10 parts water to 1 part KBS Klean. Wash the surface thoroughly, rinse well, and allow to dry completely before coating.
Step 2 — Apply DiamondFinish Clear
Apply DiamondFinish Clear in thin, even coats — never heavy. For rusted metal, a minimum of three coats is typically required.
