What is it going on? If it is a full vehicle wrap I know some people that can do it. If it is just a small section like a rocker panel, I could probably handle it.
the soap and water does not hurt the adhesive unless the soap and water is sprayed over and over for a long period of time without being able to apply the vinyl (and it would take a really long time for that to start happening). as stated it is just to allow you to move the vinyl around to the position where you want it. then when you squeegee it, you are getting the soap and water out. once the soap and water is out the adhesive starts to do its thing and tacks down, allowing you to move further and further down the side of the car or whatever. I have wrapped tons of racecars and haulers and as long as you do section by section you should be fine.
