Question 1

Do I need primer before spraying paint from a can?

Accepted Answer

Always apply primer to bare metal, aluminium or exposed plastic. On existing intact paint you can sometimes work directly if the surface is clean, dry and degreased, but a thin adhesion primer always improves the bond and durability of the topcoat.

Question 2

How do I find the exact colour code for my car?

Accepted Answer

The colour code is on the car's identification plate, usually in the engine bay, on the door pillar or in the boot. Look for a combination of letters and numbers next to a label like 'Colour' or 'Farbe'. Use that code to order the matching spray can from your paint supplier.

Question 3

Can I polish paint applied from a spray can?

Accepted Answer

Yes, but allow the paint to fully cure, at least 48-72 hours at room temperature, longer in cold weather. Wet-sand lightly with P2000 paper before polishing, otherwise the machine cuts through the thin layer of can paint too easily.

Question 4

What do I do if the spray can clogs or sprays unevenly?

Accepted Answer

Remove the nozzle and soak it in acetone or paint thinner if it's clogged. If the pressure in the can is already low, atomisation suffers and you get a dry, coarse mist, warming the can in warm water (never hotter than 40°C) helps with that. Never spray the can completely empty before storing.

Question 5

What's the difference between etch primer, surfacer and adhesion primer?

Accepted Answer

Etch primer contains acid that reacts chemically with metal for maximum adhesion; surfacer (also called high-build primer) is thicker and fills minor imperfections before the topcoat; adhesion primer improves the bond of paint to plastic or existing paint layers. Use the right type for the material and the stage in the painting process.
