Paste and powder paints should be mixed in quantities sufficient for immediate use only, as these materials often become unfit for application if allowed to stand for three or more hours.
Cheaper then doing it yourself. Some would argue that if you're going to all the trouble to fully prep the car yourself, then why not just shoot the paint as well? Why get a shop involved? The answer is simply that you'll get a better job and for less money. Some would argue with this, but the fact is that if you've never sprayed a car before then your first car will have a steep, and expensive learning curve. Laying down an even, consistent coat of paint takes considerable practice. Also, paint and equipment is not cheap. You'll need to buy primer, color coat, clear coat, reducers & catalysts. None of these are inexpensive and you can easily spend as much in paint materials alone as the cheapest paint job at Maaco or similar shop.
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.
Always use a sanding block for flat surfaces. Just your hand behind a thin piece of sand paper can leave grooves and low spots. It's also easier on your hands. For inside curves try wrapping the sand paper around a short section of garden or heater hose. This will help approximate the concave curve and help stay away from sanding through hard edges. On hard edges, like the top ridge of a fender or leading edge of a hood, you need to do this by hand. A sanding block will quickly dig right through the paint on a hard edge and take you down to bare metal. This means primer and more sanding.
PRIMARY COLORS. The primary colors are red, yellow and blue. These colors are your base colors from which all other colors come from.
Five categories are used to describe VOC content. For guidance, a minimal VOC content is up to 0.29 per cent, whereas a very high VOC content is above 50 per cent. All brands have, where necessary, reformulated their ranges to give minimal VOC content.
The reality is that the guys shooting paint, even at the cheapest shops, know how to do it. They spray a dozen cars a week and have plenty of practice laying down smooth, consistent coats of paint. They work quickly and efficiently because they have to or they don't make money. They don't really make their money on shooting paint. They profit from body work because it takes time and insurance work because it pays well.
