I have four large galvanised gates to paint. The galvanising has had a few years weathering and there is no rust. Could you tell me please what is your best long lasting paint for this - hopefully one coat if possible.
We would suggest Rust-Oleum Mathys Noxyde Pegarust, this can be applied directly to weathered galv after cleaning and degreasing - two coats must be applied though, not one.
