How To Paint A Car With An HVLP Spray Gun Step By Step?

#1. Sanding The Surface

First of all, make the surface even and smooth for the paint. So sand your car in a circular motion to bare the metal for primer and make it ready for a new coat of paint.

#3. Clean The Surface

Use a rag, alcohol, or mineral spirits to wipe down the surfaces of your car thoroughly.

If there are some oil residues, try to remove them and make them ready for painting.

#4. Taping The Surfaces

If you want to leave some part of the car unpainted, use a newspaper or masking tape to cover the surface like window trim, glass, door handles grills, and mirrors.

#5. Prime The Surface

When you sanded down your car to the exposed metal, use a self-etching primer to the surface and make it ready for further coating. Removing the rust makes it smooth to apply the primer to the areas you want to paint.

#6. Sanding The Surface Once More

Before spraying the paint coating with an HVLP spray gun, sand the primed surface once more so that the extra priming material may be scratched exposing the metal surface again for the paint coating.

Normally, you need 3 to 4 coats to cover the surface completely. But before every coat, make sure of the drying time of the previous coat. It may take almost 30 minutes to an hour.

#10. Final Sanding And Wiping

Before spraying for the last time or applying the last coat, try to sand the surfaces once more so that the powdery residue should be removed. After this, wipe neatly with a clean rag.

#11. Applying The Lacquer

When all is done successfully, now spray a coated lacquer to make it shining, glittering, and eye-catching. It should be handled most carefully with the professional painting technique.

#12. Removing The Masking Tape
