Product Information
Full details
The U-Pol HIGH5 1K High Build Paint Primer is an essential tool for automotive professionals and DIY enthusiasts looking to achieve a smooth, professional-grade finish during vehicle restoration or panel repair. This high-performance aerosol filler provides superior surface preparation by filling in minor imperfections before the final paint application, though users should ensure they are working in a well-ventilated space due to the solvent-based nature of the aerosol formula.

FAQs
Can I apply this over bare metal?
For best results, it is recommended to apply this over a properly prepared, scuffed, or primed surface to ensure maximum adhesion.
How many coats should I apply?
Typically 2-3 medium coats are sufficient to fill minor surface imperfections, with a 5-10 minute flash-off time between coats.
Is this primer compatible with all topcoats?
It is compatible with most standard automotive basecoats and topcoats, but a test patch on a scrap panel is always recommended.
Does this product require a hardener?
No, this is a 1K product, meaning it is a single-component system that air-dries without the need for an external hardener.
How long should I wait before sanding?
Drying time depends on temperature and humidity, but it is generally sandable after 30-60 minutes at 20°C.
Troubleshooting
Nozzle clogging during use
Remove the nozzle and soak it in a solvent cleaner or replace it if the blockage persists.
Primer surface looks rough or powdery
The spraying distance is too far; bring the can closer to the surface and ensure consistent, overlapping strokes.
Surface does not sand smoothly
The primer may not have fully cured; allow for more drying time in a warm, well-ventilated area.

Setup, Compatibility & Care
To ensure optimal results, shake the aerosol can vigorously for at least two minutes before use. Ensure the surface is free of grease, wax, and moisture. Apply at a distance of 15-20cm from the surface. Always clear the nozzle after use by turning the can upside down and spraying until only clear propellant comes out. Store in a cool, dry place and ensure the ambient temperature is between 15°C and 25°C during application to prevent surface issues like orange peel or poor flow.
