Stripping all the chrome. One of the single most important steps in saving money on a paint job is to strip your Mustang as much as possible yourself. This means taking off anything and everything that won't be painted. The more you take off the less the painter has to mask around. Masking not only takes their time (which costs you money) but it also results in areas that simply can't get a full coat of paint. If you take everything off, then the painters can simply scuff and spray, which will give you better and more consistent coverage.
If you have a vinyl top then remove the molding separating the vinyl and paint. Drip rail chrome really should be removed also, but can be extremely hard to take off undamaged. If you plan on buying all new drip molding then definitely remove the old for painting. But if you want to keep the originals then it might be better to leave them on and let the painter mask around. If you have hub caps it's easy to just take them off. While the paint shop should completely mask all four tires, overspray can still find its way in. It's sometimes better to play it safe and just remove wheel covers.
Acrylic is the second new name for magic in paints. This is also a plastic-in-water. Solid acrylic you know as the beautiful, glasslike Plexiglas and Lucite.
Take your time there is no rush. There is nothing wrong with having your project take a couple of weeks.
The first step is to cover the surface with a coat of paint, using your regular paint brush, or spray, or roller. Then, while the surface is still wet, take the dry stipple brush and energetically with short strokes drive the ends or the bristles into the wet paint. Be sure not to brush across. The result will be clusters of dots. Every few minutes wipe the brush with a cloth, to keep the bristle ends clean and dry.
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.
To balance, you must grasp the interconnectedness of color schemes. All these interactions are defined in the color wheel, and it has been used to build color schemes for centuries.
