most tinters use johnson and johnson baby shampoo. stick with that and u will be fine. there are other slip solutions on the market that are made for window tinting, but jnj baby shampoo works really good because of the lack of detergents in it.

Fill a spray bottle with water and add a couple of drops of baby shampoo. Spray the mixture onto the window. This mixture helps the film stick to the window but still lets you slide the film around so you can fit it properly into the corners before the mixture dries.

Freshly tinted windows should be kept up for at least 48 hours after being tinted. To be completely safe, consider keeping your newly tinted windows rolled up for 72 hours (3 days) to allow maximum curing time and avoid peeling edges.
