F.A.B.O. windshield decals

May be a stupid question but, do they mount inside or outside of the windshield?

Out side the windshield.

Does it go on upside down or rightside up?
Does the windshield have to be in the car?
Should I put it on with my left hand or my right hand?

( Sorry Tony, I couldn't resist... :D )
