sounds about right, also know that the lip will chip easily any time new tires are mounted or old ones are dismounted, so think about leaving that unpainted, otherwise you have to touch it up whenever you change tires.
Also watch out for clearcoat, as sometimes it causes bubbling and requires a whole rim to be redone.
