Cast all the way and use
edge sealer not edge tape.
Before you install the graphic, install
Knifeless tape 1/2 inch above the wake ridge line. On the front you should overlap the center line by 3" on each side for a total overlap of 6". After all the graphics are installed you need to edge seal all the exposed edges and seams. The neat and clean way is to make a paint mask with tape exposing 1/4" on either side of the edge. By doing this you can quickly paint it on with the provided dauber without it looking sloppy. They say it is ok to use edge tape but it will fail way before edge sealer.
Edge sealer is expensive but I always leave the can and the scraps with the client and explain that if the wrap gets damaged or starts to come loose they can use it to patch and or stop the damage - I install for others and usually I'm driving hours.
