Use direct-to-metal (DTM) acrylic or industrial enamel. Use marine-grade for coastal sites. Prep matters most — wire-brush rust, sand glossy, clean. 2 thin coats, not 1 thick. Total cost: $200-$500 in materials by container size. Skip exterior latex house paint — it peels in months.
Every 5-7 years inland (when patina starts looking dull or rust spots multiply). Every 3-5 years coastal (salt air accelerates everything). When original paint is failing or has bubbled.
Pressure-wash or scrub with degreaser. Wire-brush any active rust. Sand glossy areas with 80-120 grit. Tape off door gaskets + hardware. 70% of paint failures trace back to skipped prep.
Rust-inhibiting primer on any exposed metal spots. Skip primer if you're recoating over adhered factory paint. Brand: Rust-Oleum Rusty Metal or POR-15 primer.
Direct-to-Metal (DTM) acrylic — cheapest, easiest. Industrial enamel — most durable. Marine-grade — best for coastal. Avoid: exterior latex house paint (peels), oil-based porch paint (yellows + cracks).
Sprayer for smooth finish (rent or buy $200-500 unit). Roller works for budget jobs but corrugation needs careful work. Brush only for cut-ins around hardware.
Two thin coats beats one thick coat every time. Let first coat fully cure (24+ hours typical). Recoat within 2-7 days max — beyond that, re-prep.
