We had our 4' culvert inspected and were told we should treat the bottom of it for surface rust. The rust doesn't go all the way through, but we do need to treat it with something that will protect it and prevent future rust.
My husband used "Extend Rust Treatment" on cars he repaired up north many years ago and wondered if this would work. Anyone ever use this on culverts?
Anybody have any recommendations for a product that will do this?
Thanks!
Extend works well by chemically converting the surface rust and stopping it...you would need to seal the surrounding metal once rust is converted however.
