How To Paint Your Car
Masking & Preparation
To begin this venture we need to clean the metal on the car. After we clean the metal, make sure it’s dry before we begin to mask the car, also do a last minute check to be sure it’s free of all dirt grease and other contaminants.
Now it’s time to mask the car, and be sure to mask all that you don’t want painted leaving no masking hanging of the car, that would get in the way of a nice paint job. The main idea of the whole thing is to produce the best quality paint possible with the given surroundings, it is preferred that you have a paint booth, but if not, make sure that the area that you use to perform the work is ultra clean and dust free.
After the car has been masked it’s time to get ready to spray the primer, once again make sure that you have cleaned your surroundings, it’s best to have some water on the floor to keep the dust down, once you are confident that the area is clean then you can begin checking the spray guns to be sure that they are clean. This is a very important step especially if they’re not your guns, dirty guns will make an ugly paint job there for wasting all of your time.
Now that you have determined that the paint guns are clean, make sure that your respirator is in good working order. Now be sure that you have all the products that you need to perform the primer job on the car. You will need primer, reducer and catalyst, you will also need strainers, stir sticks and a measuring device.
It’s best not to have to leave the paint booth during the time that your priming the car. Reducer comes in different temperatures and you need to know what temp is best for your working conditions.
The temps are as follows, their is a high temp that is designed to dry slower when it’s hot in the area where your working, high temp is good for 80 degrees and up, theirs also a mid temp, this probably the most popular temp used this is best used from 55 to 80 degrees and is designed to dry faster to make up for the colder temp, due to the fact primer will run easier in the cold weather. Now we have low temp reducer this will dry extremely slow therefore for giving the primer a better chance to run. I tell you all this in an effort to help you better understand the products that you are working with, the more you know the better armed you are for problems when they happen.
Now it’s time to enter the paint booth, and as you do pay attention to the booth filters and be sure that they sure clean also. Now get your can of primer and read the instructions on the side, usually the mix is 4:1 or 4 parts primer to one part reducer and a cap or two of catalyst and for the best results follow these instructions. After you spray the first coat of primer, you will need to wait 15 to 20 minute before you can spray the next and so on, the way I like to do this is to give the body work areas a coat or two first to build them up. The whole reason we use primer is is to give the paint a smooth surface to stick to and give the metal some protection from the elements, it’s usually a good idea to get 4 or 5 good coats on the car.
If you are really serious about the way that you want it to look the you might want to take the primer one step farther and use an etching primer before you spray the urethane or epoxy primer, an etching primer will give the top coat just a little more to stick to. Etching primer has no building qualities there for it’s not used for smoothing out waves in your work, but it will make the primer stick allot better.
I do suggest that you always use a urethane primer,and not lacquer type,as lacquer can and will shrink urethane or epoxy is recommended for best results. Epoxy is a very hard primer to sand but it’s extremely tough, and urethane is I think probably your best choice,because it’s high building and easy sanding, their are a lot of brands to choose from, I use DuPont euro myself but it’s all up to you to choose that.
Now that your card is primed, it’s time to remove the masking, and I like to do this while it’s still a little wet for the sake of ease, just be very careful about how you do it, you don’t want to screw up all that nice work, so just take it slow and easy while pulling the masking off your car.
