- Metal furniture
- Rust prevention
- Wrought iron
- Hides imperfections
The specialist for tired metal patio furniture: an oil-based rust enamel that bonds straight over rust and uses a dimpled hammered texture to hide pitting, welds and old imperfections, so a rusty wrought-iron chair looks intentional again. The catch is that hammered coverage is very low at about 4-6 sq ft a can, the texture rules out any smooth modern finish, colors are limited, and like all oil enamels it takes days to fully harden.
Pros
- Adheres directly over rust and its dimpled hammered texture hides pitting, welds and old flaws
- Strong rust-preventive oil enamel built for weathered wrought-iron and metal patio pieces
- Forgiving to apply - the texture masks light runs, drips and uneven passes
Cons
- Very low coverage (~4-6 sq ft/can), so a bistro set can need several cans
- Textured finish only - you cannot get a smooth, modern flat look from it
- Limited color range and a slow full hardening typical of oil-based enamels

Frequently Asked Questions
- Can you paint hammered finish directly over rust?
- Yes — it adheres directly over rust and seals it, and the dimpled texture hides the pitting, welds and old flaws underneath. That combination is why it suits weathered wrought iron.
- How forgiving is it to spray?
- Unusually forgiving. The texture masks light runs, drips and uneven passes that would show badly on a smooth gloss, which makes it a good pick for a first spray project on an intricate piece.
- How far does a can go?
- Only about 4-6 sq ft per 12 oz can because of the heavy textured build, so a bistro set can need several. You also cannot get a smooth modern look from it — the texture is the finish.
