Yep lot of work to fix, I'm in the same boat after read ending Bass's car last year. I'll be fixing mine myself (with a friends help) shortly
Work involved -
Sand back whole bar
Repair cracks/dents/chips
High fill and sand back bar whole bar again to get smooth
Under coat whole bar
Spray bar and possibly blend paint into other pannels
Sounds to me like a good $300 work. Don't be a tight ass, you drive a 34 not a Datsun sunny.
