Yellowing/rust

[RJRavalli@xxxx]

Since I bought my DeLorean a year ago right around this time, I don't think I have noticed a whole lot of rust underneath on parts that couldn't be semi-easily replaced, but I have noticed some slight-to-heavy patches of yellowing and "dry, dirty" spots that bother me. Is there anything I can do to clean this up, or am I looking at some kind of expensive frame job? No matter what it is, what kind of place could I go to do help me out? Is this only a job for a DeLorean restoration/repair service? (My car is a high mileage D and has seen a lot of use and work, but it was also in the Bay Area for a number of years and I don't know the extent of the damage the saltwater air has done.)

Thank you for any help,
