About the product Our car rust-free primer contains epoxy resin, modified alkyd resin, and graphite powder. It can convert rust into a protective film, protecting the original surface while removing rust. Its usage is very simple: first remove the floating dust, oil stains and rust stains that are easy to fall off the surface of the car. After cleaning, apply anti-rust primer on the metal surface and wait for 10 minutes. It can form a protective film on the surface, which is scratch-proof, acid-proof, high-temperature-resistant, and long-lasting.
