FAQs
Does this primer need to be sanded?
Yes, for a professional-grade finish, lightly sanding the primer with fine-grit sandpaper after it has fully cured will ensure the best possible surface for your topcoat.
Can I use this on plastic?
This primer is specifically formulated for bare metal; it is not recommended for use on plastics.
How many coats should I apply?
Typically, two light-to-medium coats are sufficient, depending on the condition of the substrate and the desired level of protection.
Is it compatible with all topcoats?
The UNDER 395 is highly compatible with most automotive and industrial topcoats, but it is always recommended to perform a small test patch first.
How long should I wait before painting over it?
Refer to the drying time specifications on the can, as temperature and humidity significantly affect curing times.
Troubleshooting
Nozzle is clogged and not spraying
Remove the nozzle and soak it in paint thinner, or replace it if the obstruction persists.
Primer is running on the surface
Apply thinner coats and maintain a consistent distance from the surface; do not linger on one spot.
Primer not adhering well to metal
Ensure the metal surface is degreased and sanded properly before the next application.

Setup, Compatibility & Care
Before application, ensure the surface is completely free of oil, grease, wax, and loose rust. Sand the bare metal surface with appropriate grit sandpaper to ensure mechanical adhesion. Shake the aerosol can vigorously for at least two minutes before starting. Hold the can approximately 20-30 cm from the surface and apply in thin, even coats, allowing for necessary flash-off times between layers to prevent sagging. Store the can in a cool, dry place and turn the can upside down to spray briefly after use to clear the nozzle and prevent clogging.
