What do you need

In order to paint your vehicle correctly, you will need some important materials:

 Power sanding machine

Sanding pad

Air compressor

Paint sprayer

1200 and 2000 grit sandpaper

Cleaning solvent

newspaper

Masking tape

Primer

Enamel, acrylic enamel or polyurethane paint

Paint thinner

Facial mask

Goggles

A piece of rag

Denatured alcohol or mineral spirits

Friction compound (optional)

Don’t rush to do the proper paint job-painting the vehicle takes a lot of time, so make sure you have a few days to get the job done.

Step 1: Choose your location wisely

Before starting any actual painting, you need to find a suitable location for your DIY project. Make sure that your location has enough space for you to work around the car, and that it is well ventilated and well lit. Choose a place with electricity and the least amount of dust. Avoid residential garages because these garages usually have stoves or heaters that can cause fires when they come in contact with paint fumes.

Step 2: Remove rust, dents and trim

Make sure your paint job does not aggravate any defects-repair any visible dents, repair all rust, and remove chrome or plastic trim. The decorative strips and decorative strips can be replaced after painting.

Step 3: Sanding

Make your paint smooth and adhere to its surface-use a sanding method to sand the entire vehicle, or until the bare metal, the original primer, or at least new paint.

If time is short, the third option is sufficient-but, from sanding to bare metal, you will get the best results.

Step 4: Clean

Use a rag and denatured alcohol or mineral oil to thoroughly wipe all surfaces of the vehicle to remove all oil and prepare for painting.

Step 5: Tape surface

Use tape and newspaper to cover vehicle surfaces that do not need to be painted, including mirrors, window trims, glass, grilles, and door handles.

Step 6: Perfusion

If you sand the car to bare metal, you need to use a corrosion-resistant and self-etching primer to prime the surface of the car.

Step 7: Let the primer cure

If any rust is removed, make sure to properly prime them with feather hair until they become smooth and apply enough primer on the area. Follow the instructions on the container to thoroughly cure all primers.

Step 8: Polish again

Sand the newly primed surface again, but make sure not to sand too much and expose the metal surface again.

Step 9: Wipe

Wipe the primed surface with a cloth dipped in thinner.

When preparing to paint, be sure to follow the manufacturer's instructions and prepare the paint to be sprayed.

Step 10: Paint

Hold the spray gun about 6 inches away from the surface of the vehicle and sweep it left and right to spray paint on the thin and even coating. Generally, three to four layers will be required to completely cover the surface. Be sure to follow the manufacturer's drying time-this may vary from 20 minutes to an hour.

Step 11: Wipe

Before applying the last layer, sand the surface again to remove the powdery residue, and then wipe it with a clean cloth.

Step 12: Apply varnish

Use the same painting technique to apply a clear varnish.

Step 13: Remove the tape

While the clear coat is still wet, remove the masking tape, and then dry the clear coat according to the manufacturer's requirements.

Step 14: light yellow

Use circular motions to finish painting by polishing all painted surfaces. More importantly, you can use abrasive compounds to brighten the surface
