What is the best method for applying stickkers to the plastic of my 00 Banshee so they wont fall of in a day or two?

 

Try cleaning the plastic with alchohol first, to remove all oils and other residue.

 

After you have the plastic clean, fill a spray bottle with water and add a few drops of liquid detergent.Spray the area on which you wish too place the decal,and while it's wet put the decal on. The soapy water allows the decal to be moved around.Then use a credit card to squeegie the bubbles out.
