How long should I wait after spraying rust remover before painting the car?

[McAnna]

After spraying rust remover on a car, you need to wait for the rust remover to air dry before applying paint. However, the maximum interval should not exceed eight hours. If surface rust reappears due to high humidity or if the interval is too long, sandblasting or grinding should be performed again to meet the required standards before applying paint. Below is an introduction to rust remover: 1. Definition: Rust remover, also known as loosening agent, is primarily used to loosen rusted fasteners and lubricate non-removable fasteners, making it easier to disassemble rusted fasteners. 2. Function: It forms a long-lasting anti-corrosion protection on exposed metal surfaces, preventing new rust from forming. It is also an ideal lubricating coolant, suitable for threading on stainless steel and aluminum surfaces, effectively cleaning and drying electronic equipment and improving conductivity.
