Product Information
Full details
The Novol Spectral UNDER 395 Epoxy Primer is designed for professional automotive body shops and restoration enthusiasts who require a high-performance foundation for their paint projects. This aerosol primer offers superior corrosion resistance and exceptional adhesion, making it an essential tool for preparing metal substrates for topcoats. While its convenience is unmatched for smaller repairs, users should note that as an aerosol-based product, it is best suited for targeted spot repairs or smaller panels rather than complete vehicle resprays.

FAQs
Can this primer be used on plastic parts?
This epoxy primer is primarily formulated for metal and aluminum substrates; use a specialized plastic adhesion promoter if working on plastic bumpers.
How many coats should I apply?
For most repairs, 2 to 3 light, even coats are sufficient to provide full coverage and adequate protection.
Do I need to sand the primer before painting?
If applied correctly and smooth, it can often be topcoated directly, but for a show-quality finish, a light rub with 600-800 grit wet paper is recommended.
What is the drying time?
Drying times depend on temperature and humidity, but it is generally touch-dry in 15-20 minutes and ready for overcoating after 1-2 hours.
Is this primer compatible with all topcoats?
It is compatible with most 1K and 2K automotive paint systems, but it is always best to perform a test spray on a sample panel first.
Troubleshooting
Nozzle clogging during application
Invert the can and spray until clear; if the blockage persists, soak the nozzle in a small amount of solvent or replace it.
Primer runs or sags
Apply thinner, lighter coats and increase the distance between the can and the workpiece; allow more flash time between coats.
Poor adhesion to the metal surface
Ensure the surface was sanded to the correct grit (320-400) and completely degreased before application.

Setup, Compatibility & Care
Before applying, ensure the surface is thoroughly cleaned with an anti-silicone degreaser to remove all traces of oil, wax, and dust. Shake the can vigorously for at least two minutes until the internal mixing ball moves freely. Hold the can approximately 20-30 cm from the surface and apply in light, overlapping passes. Avoid heavy, wet coats that may lead to runs. The product is compatible with most modern automotive topcoat systems. Store the can in a cool, dry place away from direct sunlight. After use, invert the can and spray for a few seconds to clear the nozzle and prevent clogging.
