mate i dont belive scraping it because of the body, my suggestion would be:
-Buy yourself a decent MIG welder (not gasless)
-practice stick welding on some sheet metal same thickness, read up on welding car bodys (main thing is to not overheat the metal which will cause it to warp.)
-start taking off 1 panel at a time and start replacing all the rusted areas.
its not that difficult with a little practice, its very rewarding also, but first things first, drain all oils, fuids, everything, bleed everything, fill her up and get the car running, if it dosnt run then its not much use to you.... with only 44k miles, the outside may look a little rough but the inside will be great and thats what counts....
