Just a random thought I had: the weather gives a jet's paint job a battering; meaning they need to be resprayed approximately once every 5-10 years. (See [How often is a passenger jet aircraft painted?](https://aviation.stackexchange.com/q/9112/65))

Roughly what might a paint job for a 777 like the one shown in the YouTube video below, cost an airline?

Bonus: I believe afterwards that the weight of the plane has to be recalculated, so as not to affect [weight-and-balance](/questions/tagged/weight-and-balance "show questions tagged 'weight-and-balance'"). How is this calculation done?
