WHY?... Reflective film has a metallic (Aluminum) layer in it that prohibits the "breathing" capabilities, thus not allowing moisture to properly escape when material is applied wet. If a "wet" application is required... (example) such as on a dark vehicle surface in a hot/ sunny climate when the surface cannot be moved to a cooler condition, the amount of "wetting" solution used should be kept to a minimum and every attempt to remove as much liquid as possible should be employed in the use of a squeegee. Wet applications will void any warranty of the product itself. The wet solution used and it's PH balance may also greatly affect or react with the aluminum layer itself and create a corrosion and breakdown of the material. Adhesive qualities may also be greatly compromised. (This is according to my conversation with a 3M technical services rep.)
HOW?... There is a way that it can be done with two people, a simple "J" roller and 3" core tube. We used to employ the method a number of years ago when I worked for the County Roads division
Sign Shop. The description is a bit lengthy to go into detail here, but I believe you can grasp the concept. If not, I believe you know how to contact me for assistance.
