Detailing, corners, edges, post-heating & finishing details
Properly finishing the installation can make the surface seem as if it was never vinyl wrapped in the first place. Making this seamless finish requires experience, skill and most importantly, paying close attention to detail. Improper finishing can lead to revealing the surface beneath, poorly sealed edges which slowly peels over time.
Edges:
Edges refers to the space between two panels of the surface. For example: on a car, it would refer to the space between the front door and a fender.
To prepare this area, gently heat the space between the two panels and run your finger down the gap while wearing cotton gloves. This will help cure the adhesive over the edges of the gap and will also help conceal the surface beneath. Continue this process over all seams on the surface.
It needs to make sure if the car has been waxed, painted, crystal coated or not before doing the car wrapping job. It would hurt the car paint to some extent when removing the car wrap vinyl if the car has been repainted before. It is best to be the original car paint intact before doing the carwrapping job.When the car body have Scratches, damages, it needs to solve this problems first, because it is not good to car wrapping.
1. Need to wash and clean the car body before the car wrapping job. Using alcohol to wipe and clean it once again when attaching the vinyl for a certain part of car body.
2.It is better to wrap a complete vinyl to one part of car body,reduce splicing.Correct direction of closing vinyl edge is from outside to inside.
3.Edge-closing distance: when there is a gap between theparts A and part B（like below pictures shows）, when the A-side is closing, the optimal length of the edge of the remaining film is: the length of the edge of the part A to the edge of the part B.
4.At the top part of the car, make sure all the vinyl at the edge are embedded in the black strip（Like the red arrow below）.
Cutting:
Cutting requires a sharp blade or you will risk tearing the vinyl as appose to slicing it. Cutting takes very steady hands and intricacy or you may run the risk of cutting the surface and damaging it.
Opposite to what most people think, leaving more than 3mm can actually risk the integrity of your wrap. For a wrap to be installed properly, the extremities of the wrap must be completely installed on the panel. Any loose or floating material not properly adhered to the panel or acting as a flap to exposed air will ruin the integrity of that edge or corner. To seal an edge, make sure you heat and press the film into place ( we recommend 90 degree). A trick we use is having a squeegee guide the blade on edges. This gives us clean cuts and a 2-3 mm excess which is perfect.
Corners:
For rounded or sharp edge corners, heat the vinyl until malleable and push the film deep in the corner crevice. A moderate amount of heat should be used on the corner in order to fuse the area. Do not cut when film is still hot. Just like the edges, a clean cut should be made, make sure material is flush and installed without flaps and creasing.
When the edge is attached with a curvature and no stress point, the direction of stretching should be stretched to the vertical direction of the gap (as shown in the picture below, the edge needs to be retracted in the direction A, but it should be stretched downwards, that is, the direction B, this stretching method can prevent the car vinyl from being intact when it is just wrapped, but the phenomenon of stretching and rebound occurs at high temperatures).
Cutting on paint:
Cutting on paint is scary but there is a way of doing it. It takes skill, patience and a really sharp blade! Gently glide the blade over the film soft enough that you do not cut through the film but rather crease the surface of the film. This crease will allow you to pull away vinyl and making clean cuts without damaging the paint beneath.
Post Heating: very important, must do step!
Many vinyls are mainly heat activated. Basically our films are designed to be easily repositionable (low tack) before the vinyl is heated and adheres firmly (high tack) after the vinyl is heated. Once the wrap is finally applied to your surface and detailed cuts, edges, corners are set. Use your heat gun on the highest setting and run it over areas that may have been stretched, edges, corners and press the material in with a glove. ( 90 degrees releases any memory on the film, this is necessary for a longterm wrap).
When heating, you may encounter a bubble or two, simply use a pin or sharp edge, pop and remove the air with your finger.
This is probably the most important step in the wrapping process. It is also the most neglected, take your time and ensure everything is properly installed for longevity and reliability.
