higher priced jobs usually contain better materials and time preparing the job.....cheaper jobs mean break out the dynabraid air sander and wiz it down tape it up and paint it.....then wait for the shrink backs in a month or so,and fades ect needing to be redone much sooner......the dearer jobs mean wet sand windows out paint it once....rub it down wet and flow coat it....then the job last's for many years....take your pic,its horse's for course's as they say
