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.
Scuff for paint. Once your Mustang is totally stripped of exterior chrome it's time to scuff up the existing paint. The paint shop should do this also, but on the lower end paint packages they won't spend much time here. It's better for you to do it so you know it's done thoroughly.
Selecting a Shop. You should always get quotes from at least 2-3 different shops near you. This will give you a chance to not only compare prices, but to also check out the quality of work each shop has done. Ask to see cars they've just painted. Look for orange peel or excessive overspray. Do they mostly do insurance work or do they paint entire cars also? What types of cars are they working on? A shop that sprays nothing but old beaters probably doesn't inspire as much confidence as one that does insurance work for the local Lexus or Mercedes dealer.
Proper brush technique: When "cutting in" with a paint brush you should dip the brush in paint and tap the sides of the bucket on each side of the brush, leaving a good amount on the brush so you are able to minimize the times you will need to dip/load the brush. Next, take the brush and make a one foot to two foot line down the wall about an inch or two away from the trim or surface you are going to paint up next to, this is much like taking a knife full of butter and spreading it across an entire slice of bread. After, spreading the paint over the section, go back and even the paint out evenly across the section and cut up next to the trim with the brush. You want to paint up next to the trim or surfaced to be cut-in with the paint brush after you have released most of the paint on the wall, it is easier to cut in with the tips of the brush exposed and not loaded with a lot of paint.
Analyze your existing paint. The first step before determining if a budget paint job will work on your Mustang is to assess the current condition of the paint. In many cases you can prep and paint directly over an existing paint job, but only if it's in solid shape.
Step four: the key to a finished looking painting is to build it just like a house...and by that I mean layers. Paint it in the reverse order in which the eye sees it to make it three-dimensional. By this I mean paint what's farthest from the eye first, and build layer upon layer towards the eye. In other words, do the background first because it should be the farthest from the eye, then add the objects on top of that, and then add the shadows to complete the look. Ultimately it's common sense. If you paint a bowl of fruit, the bowl and fruit need to sit on top of that background, much as it would in real life.
THE BACKROUND. Collect information on the artist and the historical background. To analyze "Guernica" by Picasso, you need to know that Guernica is a town demolished by the Nazi, and you have to read up on the essential features of cubism. To interpret the image of kissing people covered by a piece of cloth in Magritt's "The Lovers", whatever you guess by looking at the painting falls flat once you know that the artist's mother got drowned in the river, and when found, a piece of cloth was wrapped around her head. So, don't rely on your skills and taste too much, there are things you need to KNOW before you start making assumptions. The historical background of the paintings itself is important. Was the artist an innovator, did he start a new trend or movement, whose steps did he/she follow? What experiments was he involved with? How was the painting perceived by the contemporaries? Claude Monet started impressionism with the painting "Sunrise. Impressions". Malevych started suprematism as a development on abstractionism, laying out the new artistic theory of the color, the form and the composition of the painting. The rough lines and raw colors in the fauvist paintings may be traced back to Van Gogh. Do you think there is something new suggested in the painting you are looking at, or is there anything at all distinguishing about it?
