Rust-Oleum 510 Fibered Aluminum Roof Coating is a metallic pigmented coating used for rust-proofing and weatherproofing metal roofs and sidewalls, and as a reflective coating for built-up roofing (BUR) and modified bitumen roof systems. Reflects heat, prevents corrosion and protects against mild acid and alkali fumes on a variety of surfaces, including metal, transite, built-up roofing and modified bitumen. This reflective coating protects low and steep slope roofs from harmful UV damage while supporting overall energy efficiency.
