What is the best slip solution mixture to apply this film? Should I add some alcohol to my slip?

Slip solution recommendations are to use dish soap, 31 drops per 3 gallons of water. Apply using high pressure spray pump or hand sprayers. Johnson's Baby Shampoo not recommended as it contains silicone which can cause streaking and/or create longer tack time. Material-On, Rapid Tack and other enhancers are not recommended.
