Preparation and Masking
- Start by clearing the car body to ensure that it does not have greases, dust, or any other contaminants. Once through, mask the areas of the car where you would not want the paint to reach. Securing a paint booth is highly advisable, however, if there would be no availability, do the procedure in a place that’s dust-free.
- After thoroughly checking the spray gun for contaminants, load it with primer and start spraying. The reducer that is mixed with the primer should reach optimum temperatures to suit the conditions of your workspace. There are different temperature grades for reducers.
- Wait for 15 to 20 minutes after spraying the first coat of primer before adding another coat. This helps avoid the corrosion of the metal and provides a smooth surface for the paint to stick. Ideally, a car should have four to five coats of paint.
- Spray the guide coat after priming your car to be able to spot depressions on the car’s body. Take great caution in removing the mask and have this done while the paint is still wet.
- To achieve an incredibly smooth finish, a guide coat must be added. Afterward, sand your car by hand with water running all over. Hand sanding enables you to be in control and produce high-quality work as opposed to using a machine. The use of a device during sanding can wear out the primer which obligates you to apply it for the second time.
- Start sanding with a 320-grit wet sandpaper to smoothen the guide coat. Fill the small low spots with primer or spot fillers depending on its depth. Use a 400-grit paper to smoothen the body after adding more primer on the spots.
- Inspect the whole car body to confirm that no bare metal or guide coat is visible. Sanding makes the primer look like the actual paint. Sand the primer till it achieves a smooth and shiny finish same as what the finished product would look like.
- Do not jeopardize the quality of finished work by going for cheap paints. This will save you money but will not give an appealing final product.
- Finalize the procedure by using a 600-grit wet sandpaper. By now, an excellent surface will be present and paint can be applied. Inspect your work to check that the body is even before cleaning.
- Use soap and water to clean the car for the final time before paint can be applied. Make sure that all areas are dry and double-check those that are not exposed which could hold water such as the cowl area, and between the doors among others. Failure to adequately dry the car will make the water get into your paint when spraying which will cause bubbles, thus, spoiling the smooth finish.
- Mask the car once more for the final coat of paint. Ensure that all restricted areas are masked and that the vehicle is clean prior to entering your paint booth.
- Conceal all the masked areas to eliminate any possibility of leakage during the procedure. Confirm that there is a sufficient amount of each material that you need such as the paint, thinner, catalyst, and sealer enough to finish the task.
- Check the setting of your paint gun especially when using metallic paint. The paints lighten with an increase in pressure and darken when decreased. Besides pressure, the appearance of metallic paint is also affected by the flow of the gun and its fan functioning. Always adhere to the manufacturer’s guide when mixing paint since various manufacturers have different guidelines.
- Additionally, adjust the air pressure accordingly at the gun head. Establish a spray pattern when using the paint gun to provide an equal density of paint on all surface being painted. Maintain the gun at an angle of 45 and 90 degrees relative to the surface to obtain an equal density of paint.
- Observe a distance of 6 to 8 inches between the tip of the spray gun and surface being painted. This avoids running the paint while spraying from long ranges which can lead to dry paint jobs.
- It is important to observe the air pressure and flow of the fluid in the gun to determine the speed at which it can be moved. Once you are through with painting, wait for the paint to dry then remove the masking.
Due to the rigorous procedures that need to be strictly followed, painting your car can certainly be demanding. However, the contribution of each step needs to be fully understood to master the perfect finish. Not only will you feel better about your work and grant you exclusive bragging rights but you would also make a potential business out of it.
