If you're just removing the loose rust and wanting to cover it, a rust encapsulator is your best bet. It will stop the spread of corrosion and make s a good base/primer for painting down the road. Can get either brush on or spray on types that will do the job.

I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things.
But thats just MY opinion!
