FAQs
What is the primary benefit of the black colour?
The black colour acts as a visual guide, making it easier to see imperfections, scratches, or uneven areas during the sanding process.
Can I use this kit for high-build applications?
Yes, the 1.8mm nozzle is specifically chosen to handle the viscosity required for high-build priming and surface filling.
Is the spray gun included in the kit compatible with other products?
Yes, the Duren gravity spray gun can be used with other automotive paints and primers, provided it is cleaned thoroughly between product changes.
How fast does the extra-fast hardener set?
The extra-fast hardener significantly speeds up the chemical reaction, which is ideal for cold conditions or quick turnaround jobs, but requires rapid application.
What maintenance does the spray gun require?
You should flush the gun with solvent immediately after use and periodically lubricate the moving parts and seals to ensure smooth operation.
Troubleshooting
Primer is clogging the spray gun tip
The mixture may be setting too quickly; mix smaller batches or check that the gun was cleaned thoroughly after the previous use.
Orange peel texture on the panel
Adjust the air pressure or try thinning the mixture slightly according to technical specifications for the temperature in your workshop.
Poor adhesion to the surface
Ensure the substrate was sanded correctly and completely free of oil, wax, or silicone contaminants before application.

Setup, Compatibility & Care
Before use, ensure the surface is thoroughly cleaned and degreased. The spray gun should be assembled by attaching the cup securely and adjusting the air control valve. After each session, the gun must be cleaned immediately using an appropriate thinners or solvent; if the primer hardens inside the gun, it may cause permanent damage to the nozzle. Store the remaining primer and hardener in a cool, dry place with the lids tightly sealed to prevent moisture contamination.
