You surely mean a weeks work! Glass has to come out, door off, wipers out, etc.Hmmm - that's pretty gross looking. Fixable, sure, but how good are you with sheetmetal? A skilled metal former/welder has at least a day's work there. Resist the urge to butter over that and paint. Needs to be properly fixed to be safe. A pillar and sill rust there make the difference between a safe and unsafe car in a frontal collision.
