The job is very easy but you cannot make mistakes. Once the two surfaces touch each other, they bond together and cannot be removed. My suggestion is to do a dry run first - put the pad up without the adhevive and mark the center line (with masking tape or marker). After spaying the adhesive, glue the center first by matching the marks and then move on to one side of the hood then the other side. Trim the edges if necessary after it is done.
