Like this, it will actually take quite a while to reach a number that is close enough to the yellow color you've chosen that you can't tell any difference (and mathematically, you will never actually reach an average of 4!)
Changing Colors. If you're keeping your Mustang the same color it is now then things stay pretty simple. Areas like the door jambs and inside of the trunk are probably still in good shape since they aren't exposed to the weather and you won't have to worry about repainting them. But if you're changing colors these extra areas will cost you. Be sure the price quote you get from the paint shop includes these extra areas. If you wait until the day you pull up with your Mustang prepped for paint you could be surprised by this extra cost.
Take your time there is no rush. There is nothing wrong with having your project take a couple of weeks.
Have plenty of newspaper around. After you clean your brushes wrap them in a plastic bag.
Ecological Paint. The "organic" paint brands, such as Ecos, which emerged in the late 1980s, heralded a new era of odourless paints, free of solvents and VOCs (volatile organic compounds) and paved the way for other companies' environmentally safe formulas. Following European legislation, the first stage in lowering the solvent content in paints and varnishes is set to come into force in 2007.
Pick a brand you can trust Companies with their own high-street shops, such as Fired Earth and Farrow & Ball, and those that sell through the DIY giants are the most accessible. However, buying paint online is increasingly popular and can bring you a wider choice, especially if you live outside major towns and cities.
Main thing to consider when considering painting exterior of your home is; How long do I plan living in this house. If your answer is any longer than 1 year, you may reconsider from painting trim only to painting exterior completely. From a quick glance, fresh trim paint will work from an aesthetic point of view, but not even close from complete protection and value points. Therefore, being fugal painting, does not always mean painting just enough to get by, sometimes costing much more in the long run.
