And, its never been more important to know your colors. Why? Because color is back in a big way! Just look at the vast variety of colors in the department stores. The salt and alum should be dis-solved in 4 gallons of hot water, after which the molasses may be added to the mixture. The resulting clear solution is then added to the lime paste, stirred vigorously, and thinned with water to the desired consistency. This whitewash has a yellow tinge when first applied, but the color disappears in a few days leaving a white film. 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.
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? You're not looking for perfection here, but you do want to eliminate every shiny spot of paint. When properly scuffed the paint should have a smooth, but dull matte finish. Purchase paint pan liners 5 for about $5. Once your done simply throw the liner out saving your paint pan and also giving you the opportunity to change paint colors without having to clean and dry the pan. Another satisfactory whitewash can be made by diluting a moderately heavy cold lime paste (about 33 lbs. of hydrated lime and 8 gallons of water) with 5 gallons of skim-milk.
