When spraying your house, it is a good rule of thumb to spray in the direction of the grain of the material. So if you have siding that runs horizontal, you want to spray in a horizontal style. Also, when you go to spray, the gun should be approximately 12" from the material that you are spraying. Do not pull the handle to spray with your hand still. This will spray a lot of paint in one spot causing it to drip. So have your hand moving when you go to depress the handle. This will give you an even look to your paint.
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.

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.

Imaginative play gives children the opportunity to work through aspects of their lives they are struggling with. It allows them the space in which to examine and change and minimize consequences of their own actions and experiment with different end results to situations. This playing helps children "work through" difficult emotional situations and to develop positive coping strategies.
