Undercoating & Corrosion ~ 62 Lancer GT
it all depends how involved you want to get,,either way it wil be a dirty long process to do it with the car assembled,,get the car up on a good set of floor jacks,,4 pick an area and try the products suggested,,,another way,,you can get a wire wheel for a drill and grind all of it off,,, get a good face shield,,if you can find some one that can do a soda blast up on a lift and mask off the out side of the car, that would be the easiest way,,but not the cheapest,,
your leaf sprinds look rusty,,would be easer to just replace and paint the new set,,,check JC WHITNEY for the rear leafs,,or see if you have a local spring shop in your area,,
after its as clean as you are willing to settle for,,,get a product called POR 15,, its not cheap,,but the name stands for paint over rust,,the stuff is killer,,its brush on, if you ever need to take it off you will have to grind it,,,it will hold cracked metal together,,there are other products that do the same thing cheaper,,,just my 2 cents
