Beyond looks, it makes wonders to keep the vehicle in order. I am a 'converted, as I have seen that a good coating protects the skin of the car much more than just "shine"* Unfortunately I do not have the tools of place where to do this myself, but I was lucky to find very good professionals at this, and they do not overcharge me as I also give them some work from third parties ... * to give you an idea, years ago I had to "resuscitate" a W126 which had been sleeping for years in a enclosed are where they were also doing paint and metal work ... paint, but also glass and chrome had all a "crusty" feel, like sandpaper. Luckily no stain or damage to the finish, but horrible to see and touch. My man looked at it, frowned a little (always does it!), said "I will need a couple days more than the usual", and returned the Merc looking like it came out of the showroom ... marvelous. Yes, I believe in good detail and proper "waxwork" 😁
