Product Information
Full details
U-Pol Reface is a high-performance 2K polyester spray filler designed for automotive professionals and DIY enthusiasts who need to achieve a perfectly smooth, level surface on irregular substrates like steel and glass fibre. Its key benefit is the ability to effectively fill deep scratches and pinholes with ease, though users should note that as a 2K product, it requires careful mixing with the provided hardener and has a specific pot life before it cures.

FAQs
Can I use this on bare plastic?
U-Pol Reface is designed for steel and glass fibre; for plastics, you should use a plastic adhesion promoter or a specific plastic filler.
What is the pot life of the mixture?
The pot life depends on ambient temperature, but generally, it should be used within 20-30 minutes after adding the hardener.
Do I need to prime after using this filler?
Yes, while Reface provides a smooth surface, you should follow up with a suitable automotive primer to ensure the best paint adhesion and final appearance.
Is this product water-based?
No, this is a 2K polyester spray filler and contains solvents; ensure you use it in a well-ventilated area with proper respiratory protection.
Can I apply it in thick layers?
It is designed as a high-build filler, but it is best to apply in multiple thin coats rather than one extremely thick layer to prevent sagging or pinholing.
How long should I wait before sanding?
Drying time depends on temperature and humidity, but it is typically sandable after 30-60 minutes at room temperature.
Troubleshooting
Filler is not curing
Check the mixing ratio and ensure the hardener was mixed thoroughly; if temperatures are too low, the curing process will slow down.
Poor adhesion to surface
Ensure the substrate was properly abraded and degreased before application; check that no moisture was trapped on the surface.
Clogged spray nozzle
Flush the spray gun with a suitable solvent immediately after use and ensure the product is properly thinned for your equipment setup.
Pros and Cons

Setup, Compatibility & Care
To ensure the best results, start by sanding and degreasing the substrate thoroughly. The surface must be clean, dry, and free from contaminants like oil or wax. Mix the product with the included hardener according to the technical instructions provided on the container.
Once mixed, the product should be applied using a spray gun designed for high-viscosity materials. Always clean your equipment immediately after use, as the 2K formula will cure permanently inside your spray gun if left to sit. Store the container in a cool, dry place and ensure the lid is tightly sealed to prevent moisture contamination.
