Product Information
Full details
The U-Pol High Build Primer is designed for automotive enthusiasts and professional technicians who need a reliable, ready-to-use solution for surface preparation and spot repairs. Its primary benefit is providing a high-quality, professional-grade finish with the convenience of an aerosol can, though users should note it is a 1K formula, which may not match the chemical resistance of industrial 2K systems for heavy-duty exterior exposure.

FAQs
Does this primer need to be thinned?
No, the U-Pol High Build Primer is a ready-to-use 1K aerosol formula.
Can I use this over bare metal?
It is best used as a primer-surfacer over existing finishes or previously applied primers. For bare metal, ensure the substrate is properly abraded.
How long should I wait before sanding?
Drying times vary by temperature and humidity, but it is generally touch-dry quickly and ready for sanding once fully cured.
Is this suitable for a full car respray?
This product is primarily designed for spot and smart repairs; it is not recommended for full panel or full vehicle resprays.
Can I paint over this with any topcoat?
It is compatible with most standard automotive base coats and topcoats, but always test on a scrap piece if using specialized paints.
Troubleshooting
Spray nozzle is clogging during use
Invert the can and spray for a few seconds to clear the nozzle. If it remains clogged, remove the nozzle and clean it with a solvent.
Primer is running or sagging on the surface
You are likely applying coats that are too heavy. Apply thinner layers and allow for more flash-off time between applications.
Poor adhesion to the substrate
Ensure the surface was properly sanded and cleaned with a degreaser before application. Avoid applying in cold or high-humidity conditions.

Setup, Compatibility & Care
Before application, ensure the surface is clean, dry, and free of wax or oil. Shake the aerosol can vigorously for at least two minutes after the mixing ball begins to rattle. Hold the can approximately 15-25cm away from the surface and use smooth, sweeping motions. After use, invert the can and spray for a few seconds to clear the nozzle and prevent clogging. Store the can in a cool, dry place away from direct sunlight and heat sources to maintain shelf life.
