Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!) Composition Wallboard. Composition wallboard usually presents no particular painting difficulties if the ordinary precautions are observed, such as making certain that the surface is dry and free from grease and oil. The painting procedure for wallboard is the same as for plaster; it requires a priming and sealing coat followed by whatever finishes coats are desired, or may be given one-coat flat or resin-emulsion type paint. You'll need a large compressor, not just the typical 20 gallon variety most of us have. This is a 60 gallon, vertical compressor with typically a 5+ hp motor. Then you'll need a decent paint gun (possibly 2; one for primer and one for color) which again is an expense. Then there's the question of where you'll paint the car. Renting a paint booth is best, but can be expensive and hard to find. You can always seal up your garage or shoot out in the wetted down driveway, but you'll inevitably get dirt and moisture into the paint.
In this section are some tips on techniques and tools that make it easier to paint your house than ever before - not the way the "pro" does, perhaps, but with much the same results. Tools, there is a wide variety of brushes and rollers to choose from, it is critical to select quality tools and maintain them. We will discuss brushes first, I use and recommend only Purdy brand brushes, they will give you the best results in terms of coverage and make the project go much easier and quicker. A Purdy brush is a little more expensive but if kept clean promptly after each use and stored properly, it will last for years and many projects. Most any other brushes out there, especially the cheap ones, are made of far inferior hair and I liken them to using a hand (or whisk) broom to paint with. Using lower quality tools will only frustrate you and lead you to assume that you are incapable of painting. You are capable! and the proper tools, materials, and advise are all you need. If your painting project will be on going for a couple of days, you can wet the brush with paint, wrap the brush up in a plastic sandwich bag and tape the plastic bag to the handle above the metal ferrule. Sealing it up will keep it from drying out, storing it flat will maintain the shape and permit you to use it for a couple of days without cleaning it. Because, after a couple of days or if it has had extended use on a hot day, it will loose its shape and start to collect a lot of dried paint on the hair, you should clean it with warm water and a wire brush. Once you have ran some water through the brush hair, the wire brush will then be used to remove the dried paint from the hair. Always run the wire brush down the entire length of the hair and never across it, to prevent crimping and damaging the hair. After you get the brush clean, spin it between your two hands, shedding as much water as possible from it. Then, using the wire brush again, comb the hair, shape/style the hair with your hands and lay it flat to dry. Once dry, if you will not be using the paint brush again soon, protect it by storing it in the paper shuck/cover that it came in and it will be like new the next time you use it. Painting in oil has long been a mysterious process the public has believed was relegated to the few and the eccentric. Artists and their lives have always been an unusual breed, but painting a large body of original oil paintings has also been a sure-fire way to drive oneself into immortality. The paintings will always be there, traveling through history, with your name on it! So by this definition it's definitely a noble profession. Think Dali, van Gogh, Picasso, Rembrandt and da Vinci. Each enjoys a lofty reputation for what others might consider crafts. And their reputations only grow bigger over time. What other profession offers that possibility? So who got the last laugh? Well, van Gogh did, of course. He's forever immortalized as one of the greatest humans to have ever lived. Not bad for someone who never made a dime in his own lifetime. But in the age of the Internet and the worldwide marketplace, artists don't have to starve anymore. I'm not starving, and I'm making money doing what I love. I can also work anywhere, whether I'm on vacation or traveling to exotic locales. I love that the most about it. I can do whatever I want and wherever I want, and post a painting for sale from Ibiza, Paris, London.... or Omaha. I wouldn't trade with anyone. And you won't either if you work at it and treat as a way to offer beauty to the world and get paid for it! To balance, you must grasp the interconnectedness of color schemes. All these interactions are defined in the color wheel, and it has been used to build color schemes for centuries.
