Hiding power comes from the paint's pigment and is affected by the manner and thickness of the application. Color retention is the ability to maintain its original color during exposure to sunlight, etc. Chalking resistance prevents the white chalky powder from forming on the surface and lightening the color of the paint. Chalking occur over a period of time. Blister resistance keeps excessive moisture from coming through the substrate and affecting the paint layer. Tip: if paint is applied over a damp or wet surface, blistering is imminent. You scuff up existing paint for two reasons. First, you want to get rid of any oil, grease or dirt trapped in the top layer of paint. This is the stuff that cleaners and degreasers can't get off. The second reason to scuff is to set up a physical bond for the new primer and paint to adhere to. You want to give the old paint some tooth so the new sticks better. Cold water paints of the casein type may be applied either directly to a plastered surface, or the surface may be first given a coat of primer-sealer to equalize uneven suction effects. The same is true of resin-emulsion paints, with the recommendations of the manufacturer of the product being given preference in case of doubt. Since resin-emulsion paints usually contain some oil in the binder, they should ordinarily be applied only to plaster which has dried thoroughly.
Take off the chrome molding around both the windshield and rear window. You can pick up a special tool at your local Mustang shop or by mail order that removes these quickly without scratching paint. Of course your paint is probably not in great shape at the moment, so a large flat screw driver will also do the trick. For some classic cars it makes sense to even remove the windshield, but classic Mustangs have chrome molding that will help cover any slight overspray. The leading brands now flag up paints with lower VOCs and produce paints that are virtually odour-free - the Breatheasy range by Crown is one example. Most leading brands now produce high-quality water-based acrylic paints which outperform the older technologies of vinyl and oils. Try before you buy Colour cards are fine for making an initial selection but you will want to see a true paint sample in situ before committing. Tester pots vary in price from £1 to £4. Paint onto a sheet of paper that you can move around the room to enable you to see the colour in different light conditions. The effect varies greatly. The window wall can seem dark while the wall opposite will be flooded with light. And of course there is a dramatic difference between natural and artificial light. Finally paint a patch directly onto the wall to gauge the colour, coverage and the final finish. Colors that are equally removed from a reference color are triadic colors. Since these color schemes can become too intense, unless they are very toned down, they are very problematic to manage. This color combination works well in a child's room, and it can be used effectively in a kitchen.
