I think you have it about right. You have to have a water tank deep enough to submerge your item in. The water is sprayed with a chemical that will disolve the carrier for the film. The item is then dunked at an angle until it is all under water. You then use a stick or something to swirl up any remaining 'print' before you pull up your item. It then has to dry and be cleared. Not sure of the thickness but I believe it is very thin. My worry would not be the thickness depending on what type of body you were going but rather the scale of the print. Thats why I asked about scale. There are many, many different prints from skulls to camo to diamond print to carbon fiber. Looks interesting but may not work for a scale model to well. If interested do a search for Hydro Graphics and you will find a bunch of sites. Not sure how to place a link but I will try.
