About the product Our rust-free primer contains resin, rust inhibitor. It can reduce the probability of coating failure. Its usage is very simple: remove the floating dust, oil stains, rust stains that are easy to fall off the surface of the painted object, and after cleaning, paint the metal surface. After applying the rust-free primer, the original rust turns into a composite film with strong adhesion. Wait for 10 minutes, and the rust turns into black primer. And it can be artificially rusted for too long, with high labor intensity, incomplete rust removal, and partial secondary rust removal.
