That's not too bad and no matter how smooth it looks you don't want that much bondo. It will not last as long as you will. A thin skim coat is fine.

When my son and I were putting his '54 Stude wagon together, a frame off job, so he could take it to college in Texas we ran out of time. We had door windows installed on the way. We drive all day and worked on it at night. I stayed in Lubbock for a week finishing up little stuff before I flew home. Within a month or two he blew a tranny (supercharged 289 Stude V8,Big tires, posi rear end, 18 year old driver) Lucky for us we had hooked him up with a great guy who was the president of the local Studebaker Drivers Club. Those guys are great. So when you get to Purdue find the closest Inliners. They'll love having you around.
