Our Story
We Make Your Paint Jobs Last!
A phosphoric-acid metal treatment—not a paint. OSPHO works like a rust converter: it changes rust so you can prime and paint trailers, boat steel, fences, and more. Paint adheres tighter so your job lasts longer.
The original rust remover since 1917: Rust-i-cide dissolves and removes rust to prepare bare metal for paint—ideal when you need a rust remover for chrome, hardware, enamel stains, and shop projects.
