Do you think it would help to soda blast it? It doesn't matter to me how it looks..its going to be a garage queen for a long while..I just don't want it to get any worse.Kevin,
Not much you can do with that as a short term fix other than trying to hide it with some touch up paint. The rust will break through in short order, though.
Yes you will find several more areas once you remove the paint...trust me. I saw a car show once that showed a product that you plug in to your home electric and put electric pads on your car. It puts a low voltage charge through the metal and is suppose to stop further rusting. I believe I saw it on Dream Car Garage.Blasting and getting rid of it are the best solution, I just wonder what else you will find when you start getting into it. Also, this may ( and probably will ) take you down the road of more body work than you are planning on right now.
