A car with an excellent paint job is one of life's true joys. It's like being the kid with the best bike in the neighborhood or the biggest piece of birthday cake. Whether you drive a '47 Eldorado, a '66 Beetle or an '07 fortwo, a great paint job will take your vehicle from ho-hum to headturner.
Actually creating a great automotive paint job takes skill and finesse. Automotive painting is one of the most arduous and painstaking tasks in crafting an automobile. It can also be one of the most costly. If you are on a budget, there are options for you. Some paint shops can deliver a good paint job for a fair price. Your other option is to take on the task yourself. If the paint job is a success, you'll have even more to brag about: a hot set of wheels AND a "do it yourself" tale to tell.
Achieving a great paint job is a step-by-step process. You simply can't rush automotive painting. Follow the basic steps of preparation, primer application, blocking, final paint coat and detail application. This can seem like a daunting task for any beginner, but the entire job can be completed in just a few days.
Prepare
Before you begin, check with local bylaws and regulations regarding the use of spray paint in homes and enclosed areas. The last thing you need is a legal holdup delaying your painting job.
Cleaning the car is your next crucial step. The car must be spotlessly clean and free of dirt. Use detergents to clean the car top to bottom, and then follow up with grease removers. After the car has been cleaned, it's time to begin sanding. An air sander (preferably a dual-action sander) should be used to remove the old paint from the car. This kind of sander will not cause body damage because it removes paint without digging like other sanders and grinders. Every trace of paint must be removed to create a perfect palette for your new paint job. Automotive detailing tape or even duct tape can be used to cover and protect other parts of the car, including plastic moldings and windows. In addition to removing the old paint, all traces of rust have to be sanded off. Rust will spread if ignored or untreated, and the last thing you want is body rot happening beneath your spiffy new paint. You can repair minor body flaws on the car's surface using fillers. Shape the compound with care using a sanding board, then follow up with a glazing compound. This step will help to ensure a smooth-as-glass finish on your ride.
Mask
After the whole car has been initially cleaned, then sanded, a final cleaning takes place and the vehicle is ready to be masked. In this step, every part of the car that shouldn't be touched by paint is covered and protected. Remember, you will be using high-grade automotive paint that doesn't wash off with water. Cover your windows, every light and reflector, all window rubbers, all chrome, tires, wheels, door handles, wipers.. take a good look and what needs to be masked. If you don't want even the tiniest bit of over spray on it, cover it up! The tools and materials needed for masking are available at automotive supply warehouses and hardware stores.
Prime
Priming is an essential step to providing a good foundation for your new paint. A flawless prime coat will help you to achieve a perfect paint job. Valspar epoxy is a good primer choice, combining dependable filling capabilities with minimal shrinking. After the primer has been applied, a second coat in a contrasting color should be applied on top of the first layer. This will serve as a sanding guide. The primer should be sanded to a smooth finish, but don't sand too vigorously or you could actually damage the body of the car. When the priming is complete, a sealer is applied and a final sanding takes place.
Finishing off
In finishing off the automotive painting, it is essential to achieve uniform color. The spray gun should be held ten to twelve inches away from the body to avoid streaks and runs. This is necessary when applying the basecoat, final coat and clear coat.
Regardless of the type of car you drive, a new paint job can turn it into a real showstopper. Automotive painting can be a time consuming task, but you can do it if you take it step by step. The creative energy will be good for your soul, and the compliments you receive will be great for your confidence.
Whether you are just interested in re-spraying a small area to cover up some paint chips, or want to treat your car to a custom paint job that will let you enjoy envious stares from every pedestrian you pass, you will need to follow a few basic rules, and have the right tools to hand in order to carry out the work to a high standard.
The first thing to mention about auto paint jobs is that you should always work in a well ventilated area. Paint fumes can include a number of solvents that can leave you feeling light headed and even poison you if you inhale them, so make sure there is free passage of air through your work shop when you are painting. You should also wear a respirator mask during painting or preparation to avoid inhaling any paint and loose dust that you release.
To get the best effects when painting, you also need to make sure that you are able to keep dust to a minimum. You can achieve a good environment by hanging sheets from floor to ceiling in the area where you are working, and wearing overalls. You should also vacuum clean the area where you are painting at the beginning of every session.
When you apply auto body paint, the main thing is to get a good even finish that looks good, and the key to getting a good finish is having a good start. Preparation is everything in paining. Get it right, and you will be able to enjoy a fantastic smooth finish that will last for years and look great, skimp on your preparation, and your finish will look shabby straight away, and then get worse over time.
Before you paint, you need to strip off the old paint job. You can do this with a solvent based paint remover, or do it the hard way by sanding back the panels to bare metal using a sander. Whichever method you choose, you need to make sure that you have a very smooth base. To achieve this, use the finest grade abrasive paper available, and be prepared to put serious time into the job.
Once you are satisfied with your base, you can start applying the primer. Use a HLVP spray gun connected to an air compressor, as this is much more even than an aerosol, and will be much cheaper in the long run. You should use long sweeping strokes in a single direction to get a good base to paint onto. After every coat, allow the paint to dry, and then sand it back to a smooth surface. Then apply the next coat in strokes that go at 90 degrees to the previous layer, as this will produce an even color.
There are two types of auto paint that you can use on a car, cellulose based and Two Pack auto paint. Most painters now use Two Pack because it gives a better finish, and metallic colors are available, whereas cellulose paint can be tricky to deal with, and is best used on classic cars where you are trying to recapture an older style.
As with the primer, you should apply the auto paint in coats, spraying in a single direction, then sanding back to a fine surface to remove any imperfections, before applying the next layer at right angles to the previous one.
In between coats, it is imperative to clean the nozzles on your HVLP spray gun, as otherwise, small flakes of dried paint can be caught up in the spray and cause imperfections that will spoil the final effect.
Once you are satisfied that you have got a good covering and applied enough coats of auto body paint to create an excellent finish, apply one more coat for best effects, allow it to dry, and then sand back for a smooth finish. You should leave the paint to dry completely for 24 hours and then apply a wax polish to the whole body in order to protect your new paint job and give it a shine that will certainly catch the attention of anyone you pass on the road.
