What I’m really gathering from this post is that basically, the main and biggest difference is the installer.
In my case, both were excellent!
I chose a different one from the one I used for the F83 on the G83, because he also did the mods, something that the first one didn’t do.
It just happened that he uses Vallor and the prior uses XPel.
So far…VERY happy with both products and very happy with the top notch service received from both installers.
I guess the bottom line is…check, double-check and triple-check the installer you’re going to use prior to getting your car in through the door.
Products are not that different…everyone has their preferences, the person who installs it makes ALL the difference in the world!
Good luck to all and drive fast, do it carefully and ALWAYS watch out for Smokey
