FAQs

Can I use this on plastic bumpers?

Yes, but ensure the plastic is properly cleaned and potentially treated with an adhesion promoter if the surface is particularly difficult to bond to.

How long does it take to dry?

The product is designed to be fast-drying, but exact times vary by ambient temperature and humidity. Always check for a fully matte finish before sanding.

Do I need a clear coat over this?

Yes, this is a primer designed to be a base layer. It must be top-coated with an automotive paint or clear coat system for protection.

Is it suitable for large panels?

While possible, this product is specifically optimized for spot and smart repairs. For full panel coverage, a spray gun system is generally more cost-effective.

Does it come in other colors?

This specific variant is formulated in black, which is ideal for darker topcoats or to highlight surface imperfections during sanding.

Troubleshooting

Nozzle clogging during use

Clear the nozzle by turning the canister upside down and spraying for several seconds until clear, or remove the nozzle and soak in solvent.

Poor adhesion or flaking

Ensure the surface was properly degreased and sanded with appropriate grit paper prior to application.

Surface feels rough after drying

Ensure ambient temperature was within recommended ranges and use a finer grade of sanding paper to level the surface.

Setup, Compatibility & Care

Before application, ensure the surface is thoroughly cleaned, degreased, and sanded to remove any rust or loose paint. Shake the aerosol canister vigorously for at least two minutes before use to ensure consistent pigment and binder distribution. Apply at a distance of 15-20cm using steady, sweeping motions. After use, invert the canister and spray for a few seconds to clear the nozzle, preventing blockages. Store in a cool, dry place away from direct sunlight and reach of children to maintain propellant integrity.
