My resto started with the scraping,followed by media blasting,only to find myself doing half the job.
I decided to take the whole car appart (one day) and have the whole body hot tanked!
Followed by a dip in a electrolitic derusting,then a dip in a zinc phosphate tank.
This cost about 2 grand canadian,but was THE best way of properly restoring the car.
The whole car got blasted with an etch primer,and the cavities were injected with por-15.
Unfortunately,it took me a couple of weeks to reasemble.
good luck!
