I appreciate when a "service" involves using a multi-function machine specific to the task, but I have a problem with them trying to sell a "service" when it's just a higher priced bottle of chemicals.
At the same time, they have orange stools. Orange stools always impress me! lol.
I think it was all staged though, kind of laughable that they show people working on the engine in dim light for scenic effect, when you kinda want a well lit room instead.
