Product Information
Full details
The Octoral C401 is a high-performance HS420 gloss polyurethane clear coat designed for professional automotive refinishers who require a durable, high-build finish that dries efficiently without the need for forced baking. It is ideal for shops looking to combine premium protection with excellent flow characteristics, though users should note that as an air-drying product, it requires careful monitoring of ambient shop conditions to ensure optimal curing.

FAQs
Does this clear coat require a baking oven?
No, the C401 is specifically engineered for air-drying, making it ideal for shops without baking facilities.
Can I use this over any basecoat?
It is compatible with most standard automotive basecoats, but always test for compatibility if using non-Octoral systems.
How long does it take to dry?
Drying times vary based on ambient temperature and airflow; consult the specific technical datasheet for precise touch-dry and polish-ready times.
Is this a single-stage or two-stage clear?
This is a two-stage clear coat, intended to be applied over a basecoat layer.
What is the shelf life of the 5-litre container?
When kept sealed in a cool, dry environment, it maintains its integrity for the manufacturer-specified shelf life, typically printed on the label.
Can I polish this clear coat?
Yes, once the product has fully cured, it is designed to be easily sanded and polished for a show-quality finish.
Troubleshooting
The finish looks dull or hazy
This is often caused by trapped solvents or high humidity. Ensure your flash-off times are adequate and humidity is below 70%.
Orange peel texture appears
Adjust your spray gun pressure, increase thinning slightly, or reduce your travel speed to allow the product more time to level out.
Runs or sags in the clear coat
Check your gun overlap or reduce the volume of material delivered; you may be applying the coat too heavily.
Pros and Cons
Pros
- Dries efficiently without expensive baking equipment
- High-gloss finish with excellent depth

Setup, Compatibility & Care
Ensure the application area is free of dust and debris, as the high-gloss finish will highlight any surface imperfections. The C401 should be mixed according to the technical data sheet ratios regarding hardener and reducer, using high-quality spray equipment with a 1.2mm to 1.4mm nozzle. Before application, ensure the basecoat is fully flashed off as specified by the manufacturer. After application, allow the panels to cure in a clean, ventilated area. Always store the lacquer in a cool, dry place with the lid tightly sealed to prevent moisture contamination, which can cause the product to skin over or cure prematurely inside the container.
