Spraying is not somthing you can buy a book on then know how to do. Just takes time and expirience. And it's right about the patience....

Buy yourself a gun, and a panel, and some paint, and just keep at it till your happy with it. Practise makes perfect.

It's all about your preparation, the more time you spend preparing your panel/car/whatever, the better your finish will be.

And don't give up when you make a balls of it. Cos, you will make a balls of it
