The right answer
before the next coat.
These are the questions that come up when a repair needs to be clean, durable and ready for the next stage. Use the search or browse by topic.
Which primer should I use for an auto body repair?
The right primer depends on the surface, the repair and the paint system that follows. For bare metal, repaired areas and previously painted panels, match the primer to the substrate and follow the product technical data sheet. If you are unsure, send us the repair details before ordering.
What is automotive body filler used for?
Body filler is used to shape and level suitable repaired areas before priming and painting. Apply it to a properly prepared surface, keep applications controlled, sand it smooth and avoid using filler as a substitute for repairing badly damaged metal.
Do I need a hardener or activator with my paint?
Some two-component systems require a specific hardener or activator to cure correctly. Always use the product’s stated mixing ratio and compatible components. Never guess a ratio or combine products from different systems without confirmation.
What does clear coat do on a vehicle?
Clear coat provides a transparent protective layer over compatible basecoat systems and contributes to gloss, depth and durability. Surface preparation, flash-off times and the correct activator are just as important as the clear itself.
Which spray gun is best for primer, paint or clear coat?
Choose a gun and nozzle setup suited to the product viscosity, the area being repaired and the finish required. Primer often needs a larger nozzle than basecoat or clear. Check the product and spray-gun manufacturer guidance, then test your fan pattern before spraying the panel.
What sandpaper grit should I use for automotive bodywork?
The correct grit depends on the stage: heavier shaping needs a coarser abrasive, while primer preparation and final refinement use progressively finer grits. Move through the grades rather than jumping too far, and keep the surface clean between stages.
Why is masking important before spray painting?
Good masking protects glass, trim, adjacent panels and surrounding surfaces from overspray. It also gives cleaner edges and reduces rework. Use suitable masking materials and make sure edges are secure before spraying.
Can I use automotive spray paint for a small touch-up?
Aerosol paint can be practical for smaller repairs and touch-ups when the surface is properly prepared and the paint system is compatible. Colour accuracy depends on the vehicle’s paint code and the condition of the surrounding finish.

How should I clean a spray gun after use?
