Had my brand new car done at Revol 2 weeks ago and have nothing but fantastic experience so far! Here is the finished work on my car for reference (last black activehybrid 3 on page below)

I can't recommend Gavin and his team enough. Right from the moment i made appointment, stepped into his workshop and 2 weeks on, I still have a smile on my face (can see it on the gleam on the car!). The service was impeccable... when i got back to the workshop to collect my car, it was not ready but Gavin took me personally in his car to a nearby mall to grab lunch! How is that for service?
As for the shine, so far so good (see pics).... still using water only to wash the car and the shine is still there! I am sure there are other good paint protection services out there but i think it would be hard to beat this level of detailed work and service of Revol!
Thanks again, Gavin!
