This failure on the bonnet is most likely a combination of bad quality film and bad technique. While higher quality vinyl can stretch to 30% giving you the ability to work it into shapes and dips in panels. the installer has stretched the vinyl out over the entire bonnet and then forced the vinyl down into the grooves running up the bonnet. the result of this is a huge amount of tension being placed on the film meaning over the course of the first week or so the vinyl has quite literally pulled itself back up from the tension.
Here you can see a join and overlap running through the middle of the quarter panel from the tail light all the way to the back doors.
This technique is used to avoid having to do from the dog leg panel, across the quarter panel and all the way up and over the top of the doors the the windscreen in one continuous piece. its lazy and incorrect.
here we see where the roof has been laid back to the aerial then sliced from the front of the aerial through the remaining vinyl. its then been pushed and forced around the aerial marring the vinyl. it has then been overlapped behind the aerial melted with a heat gun. the vinyl has then been cut around the aerial but up on the rubber, doing this leaves it prone to water entering under the vinyl and lifting as you can see at the back of the aerial.
The way in which bumpers are approached is very important as being such a multi dimensional shape means during the process you can end up with alot of excess vinyl in areas or extremely high amounts of tension in areas. while tasteful and discreet infills and capping pieces are often a requirement when doing a bumper the places in which the installer chooses to put them can define weather it will be a nice finish or end up like this mercedes. As you can see around the spotlights the installer has used an infill technique, the idea behind this is to relieve excess tension by not having to force the vinyl around the spotlights, however the installer has stretched the infill and pushed it in regardless which has caused it all the spring back up. another thing to note is that joins should always be executed at a radius downwards or away from the eye.
In the lower air intakes the installer has fitted infills, then during the process of cutting the holes has put the knife blade so far through that it has dragged on the infill slicing a section along the bottom, this has pulled apart later down the track exposing the silver underneath.
At the headlight and taillight sections of the bumpers there are areas where excess film has been shrunk using heat trying to get rid of excess and baggy film, the issue with this is the vinyl is designed to stretch to 30% but isn't really supposed to be shrunk down. as a few weeks go by and the film starts to return to its natural size forcing it to bunch up and out as this is the only way for the material to go.
The bad finish on the mirrors is due to them not being dismantled before installation. it is often necessary to have stretched sections of vinyl wrapped around the back of the panel to anchor it. This will stop it pulling away from the edges. Its a similar story with the door handles.
The biggest problem with this job aside from the shoddy installation was the way it was approached. when doing a quality vehicle wrap attention to detail is of great importance. This amg was not stripped down properly for the job. To wrap this car professionally the bars needed to be removed and the individual components of the bar needed to be removed from them. The door handles and top trims should be removed, the mirrors should be removed and dismantled, the aerial should be removed, the head and tail lights should be taken out, the boot lid and garnishes should be dismantled. the general feel of lazyness comes from this car, the installation was extremely unprofessional and the way the car was put together defied belief with bolts missing or only half fastened.
The cheaper option.
There is a saying in life that says "the poor man pays twice" once to have it done and once to have it done right. The same applies to taking the cheap option.
