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.
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.
Definitely good inside the house is a new vinyl primer-sealer to be used as a base coat under any paint. It dries in as little as 30 minutes.
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.
Is some color dominating?
Concrete Floors. Two general types of paints for concrete floors are varnish and rubber-base paint. Each has its limitations and the finish cannot be patched without the patched area showing through. Floor and deck enamel of the varnish type gives good service on concrete floors above grade where there is no moisture present.
CLEAN-UP and STORAGE or DISPOSAL TIPS. · If there are paint drops on your floor, don't let it stay there. As the paint sets longer, the harder it will be cleared. Use a cloth with soap and water or a solvent for cleaning. · Use a razor-blade scraper or a putty knife to chip off bigger paint droplets that have dried. · Use a scraper to trim around windowpanes. · Wash and dry paintbrushes and rollers. Store them according to the brand's recommendation not all paintbrushes have the same type of bristles nor the rollers have the same material. · Clean the paint from the rim of the can. Tap container lids tight with a hammer and block of wood. · Store solvent-based paint cans upside down to prevent a skin from forming. · Store your paints in normal or room temperature. Never put the paints in extreme hot or cold rooms. · Each states in the U.S. or every community/ county differs on paint can disposal methods. Check your local environmental, health, and safety laws.
