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.
If you are grappling with the problem of choosing a woodwork colour to go with neutral walls, check out Architectural Colours by David Oliver, the founder of Paint & Paper Library. He arranged his off-whites for ceilings, cornices, walls and woodwork in chromatical groups and the concept has been so well received that chromatically arranged colours, such as soft greys, greens and pinks, have been introduced.
Also, when checking the paint, be realistic and don't ignore areas just for the sake of convenience. It will cost you more in time and money later. Typically if one area of the paint is cracked or peeling, then the paint on the entire car is suspect. Maybe the rest of the car just hasn't quite reached that point of decay, but it will shortly. So if you only fix areas that look bad, you'll likely find that you wasted a paint job when the other areas start to crack or peel in a year or two.
Better still, you don't have to spend hours getting ready and hours cleaning up afterward. Premixed paints, electric-drill attachments and self-dispensing calking guns make short work of preparation. Cleaning up is a soap-and-water job for the rubber paints, or a quick dip in special cleaners for the oils. Disposable dropcloths and paper paint pails are used once and thrown away.
Painting ceiling does not require premium paint. You can use flat $15 to $20 ceiling paint. I use Sherwin Williams PRO-MAR 200. Painting ceiling requires a lot of physical work and plenty of drop cloths. If you are not up for the challenge or have very high ceilings contacted a professional will prove to be a smart move.
After the siding of your home is painted you can now start on painting the trim. There are a couple different ways you can go about painting the trim of your house. The first way is to mask off all of the trim so that you can merely spray the trim color on to your house, and the second way is to roll the trim by hand. If you are the only person painting the house I would recommend rolling the trim by hand. The reason being is because it takes a long time to mask off all of the trim on your home compared to just rolling the face of the trim boards. If you have multiple people, it would be faster to have the helpers mask everything off while you start spraying the trim color.
Types of Paint. Water-based paints are usually referred to as emulsions and were traditionally used only for interior walls and ceilings. But recently tremendous advances in paint technology mean that water-based formulas, especially the high-performing acrylics, are available for all surfaces, from woodwork to metal, and for interior and exterior use. The advantages of these paints over oil-based ones is that they are cleaner, have less odour and are more environmentally sound. Brushes can be rinsed clean with water.
