Watch a few youtube videos about PPF installation to get a better understanding of the nuances. The experience and skill of the installer is very important and it is not worth scrimping for poor quality work. It comes down to how well the seams are hidden and the little details that have to be done freehand.
Personally, I did not want any seams on the front facia under the fog lamps since they will collect road dirt over time and become noticeable. XPEL provides cutting templates to their installers that can be used to cut out exact pieces on site. Unfortunately, the template leaves a vertical seam at the bottom of the fog lamp corner. I spoke to Goldwing ahead of time with this concern and they said they use single sheets and cut to fit on the vehicle- perhaps did this just for me since I asked about it but I dont think so.. That is one example of many where the skill and experience come through.
It best to see to look at some of the installer's work both new and after a year of so. I was lucky in that when i went in they had just finished the same package on a new black Model Y and i was able to have a good luck at their work.
BTW, it is not like their prices are cheap either or did i pay too much? hmmm
Thanks. I have a few quotes for full PPF and I am finding about $1500 variation among 6 companies in Ottawa so it is enough to take pause.
