I use 3 drops of dawn dish soap (or any fancy smelling dish soap your wives may have, i wont judge here) per 24oz spray bottle of water. Provides the best amount of slide/stick for the decal. When your happy with where its placed, start squeegeeing out the liquid and air from the middle, outwards. Or if you have measurements, make an L shaped template with 1/2" masking tape and again, once your happy with the placement, start squeegeeing out the air and water from one end and work to the other using the template to ensure correct placement based on your measents. Hope this helps. This method has always worked for me.
