I just got a 1971 red super beetle, and have today stripped out all the seats and floor to the bare metal. I have a bit of a rust problem, though it's not so bad considering the car's age. What steps should be taken for the rust? Advice appreciated.



Under the battery.




Left side of under the back sea, above rear wheel arch - is a rust hole here dangerous?




Under drivers seat, im guessing anew plates welded onto bottom..?

Inside the floor vents.
