Painting trim is normally done by roller and brush, not sprayed, so more manual labor is required painting trim, and most cases costing 60% of the total exterior painting job. 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. Definitely good inside the house is a new vinyl primer-sealer to be used as a base coat under any paint. It dries in as little as 30 minutes.
HUE-VALUE-INTENSITY. Hue: Without getting too technical, and to put things into laymen's terms, hue is just another word for color. For instance, grass and leaves are two variations of a green hue. We are living in a highly pressurised and competitive world. There are more people chasing fewer jobs and in order to compete and survive in this world our children need to be as highly educated as possible. This has led parents to pressurise play-schools and nursery schools to begin teaching children reading, writing and arithmetic in the hope that they will be better prepared for formal schooling when they enter grade 1. Proper rolling technique: When rolling paint on the wall, get the roller skin evenly loaded with paint and make a V,N or M pattern on the wall, this is to spread the paint across the entire section you will be rolling, then roll back across the section and even out the paint. To properly "lay off" each section, make a final pass of the section applying light pressure to the roller frame arm end of the roller skin and bringing the nap mark (mark created on the pressure applied side of roller skin) across from the beginning of the section to the end of the section, and just repeat all the way down the wall.The V,N or M pattern, will be determine by how far the paint will spread, a V is for less spreading paint and M is for farther spreading paints. Do not "dry roll", which means trying to roll to much of a section at once with very little paint on the roller. Just as important, do not apply to much, if you find you are applying to much, increase the size of the section you are painting i.e. from a V pattern to an N or a N pattern to a M. Once you figure out which position is prime and which position is spray, place the valve in the prime position and grab the primer hose. Point the primer hose in the empty bucket near the top and at an aproxx.45 degree angle from the side (the reason for this is that there is likely to be pressure still built up in the airless and when you first switch on the airless to prime it, paint will likely burst out of the primer hose and you don't want to have it go everywhere). Now turn the airless paint sprayer on and you will see that the airless is sucking up the new paint and pumping out the primer hose. At first you will typically see a cleaning solution come out followed by your paint. When you see your paint coming out switch over the primer valve to the other position and you will see the airless pumping paint into the main hose.
