Here is the best place for ready made Sprays that i can find!! Many different types to fit your needs:
AtomicWarrior.com Now you picked out your spray,but how do you get it to work on Steam?
1.Make sure your wad file is RENAMED to tempdecal (make file a READ ONLY)
To convert wad to read only-right click-go to properties-click on read only--then apply.
To rename file--right click on pldecal file, rename to tempdecal.
2.Place in: Steam/steamapps/email/day of defeat/dod.(click and paste)
3.Now, in dod folder-double click on config folder--open folder with notepad:
4.Remove files such as: cl_logo color and " #Valve_yellow" or cl_logo"lambda" #Valve_orange
To try out your new spray--create your own game/then spray,remember that not all Servers will allow you to spray.

If you dont like what you find in Atomic Warrior, you can make your own with a program called Wally. I will place it on the downloads page.
