First, clean the entire surface where the decal is going to be applied. Next use tape to hold the decal where you want it. This may require two people. One to hold the decal while the other put pieces of tape in place.
Next, use a razor blade and carefully cut the decal where all seams or separations exist. For example on this job 3 cuts needed to be made so the doors could be opened during this procedure. Note: Mix a drop of soap into a cup of water, and use a little of this solution to dampen the smooth surface you will be applying the graphics to. This will buy you a little time while you make sure it’s straight and help reduce bubbles. Don’t use much though!
Now that this decal is cut into pieces, (front fender, front and rear door and rear quarter panel), 4 strips of tape were put up the center of each portion for use in the steps ahead. Next lift each 1/2 of the decal sections, one side at a time. Cut the backing paper from each 1/2 off and squeegee the decal from the center and work your way outward. This should be what you are seeing with the first half of the first portion being applied and notice the left half still has the backing paper on. Once that 1/2 of the first section has been applied you can take the tape off that piece of tape and the remaining backing paper.
Squeegee the second half, completing the first section. The first section you should apply is usually the smallest section of the decal to get a feel for how this is done and you will feel more comfortable doing larger areas. With the first section complete, remove the transfer paper GENTLY by peeling it back at a 45 degree angle.
