FAQs
Can I apply topcoats directly over Spectral UNDER 395?
Yes, once the primer has cured to the manufacturer's specifications, it serves as an excellent base for most automotive topcoat systems.
Is this primer suitable for plastic bumpers?
This product is primarily formulated for metal surfaces; for plastics, consider using a specialized plastic adhesion promoter instead.
How long should I wait between coats?
Follow the ambient temperature guidelines on the can, but generally, wait 10-15 minutes between light coats to allow for solvent evaporation.
Does the grey colour affect the final paint colour?
No, the light grey is specifically chosen to provide a neutral background that helps you achieve consistent colour coverage without changing the final hue.
Can this be used for internal engine bay parts?
Yes, its corrosion-resistant properties make it suitable for engine bay components, provided they are cleaned and prepared correctly.
Troubleshooting
Nozzle clogging or uneven spray pattern
Invert the can and spray for 3-5 seconds to clear the valve, or soak the nozzle tip in lacquer thinner if dried paint is obstructing flow.
Primer peeling after drying
Ensure the surface was adequately abraded with fine-grit sandpaper and thoroughly degreased prior to application.
Surface feels rough or gritty
Maintain the correct distance from the surface; spraying too far away causes the droplets to dry before reaching the metal, resulting in overspray.

Setup, Compatibility & Care
Before application, ensure the surface is completely free of dust, grease, and silicone residues using an appropriate surface cleaner. Shake the aerosol can vigorously for at least two minutes before spraying to ensure the pigments and epoxy components are thoroughly mixed. After finishing, invert the can and spray for a few seconds to clear the nozzle, preventing clogs for future use. Always wear appropriate respiratory protection and work in a well-ventilated area to avoid inhaling vapors.
