Dmz73,on the a pillar i scrapped all the old seam sealer off,removed the door hinges to rebuild and also cleanup the surronding area where the hinges were mounted,then sand blasted the entire area with silica sand.sand blasting makes one heck of a mess but nothing can beat it if you want to get every pit clean of rust.
if you need any other pics,let me know and i will post some more.
hopefully one of these pics are what you were looking for.......dave............
