Welcome to this very good forum Stevo.
The shine you will see after any paint protection treatment will depend on the colour of the car. The protection is the same. This is my VG car a few months ago after 6 months and 6000 miles since Gtechniq as done, pretty good in my opinion. It was Gtechniq black with Exo I think, with a 7yr warranty. I wash my own car very carefully every time, mostly a no-contact wash. The photos were taken in Germany after after I used a nearby car wash with foam and jet wash after a 700 mile journey.
