FAQs
Can I apply this primer directly over bare metal?
Yes, it is designed for excellent adhesion to bare metal and serves as an effective anti-corrosive layer.
Is this primer compatible with all topcoats?
It is compatible with most standard automotive paint systems, but it is always recommended to perform a small test patch.
Does this product require a hardener?
No, as an aerosol formulation, it is ready-to-use and does not require manual mixing with external hardeners.
How long should I wait before sanding?
Wait until the surface is fully cured and dry to the touch, usually following the drying time guidelines on the can, typically a few hours depending on ambient temperature.
Can I use this for plastic bumpers?
It is primarily designed for metal surfaces. For plastics, use an appropriate plastic adhesion promoter prior to applying the epoxy primer.

Ensure you are holding the can at the correct distance and avoid spraying in windy or overly humid conditions.

Setup, Compatibility & Care
Before use, ensure the surface is clean, dry, and free of grease or rust particles. Shake the aerosol can vigorously for at least two minutes after hearing the mixing ball to ensure the chemical components are properly blended. Apply in a temperature-controlled environment, ideally between 15-25 degrees Celsius. Keep the can upright and spray at a distance of 15-20 centimeters. After use, clear the nozzle by turning the can upside down and spraying for a few seconds until only propellant comes out to prevent clogging. Store in a cool, dry place away from direct sunlight.
