that aquaries body looks better than yours. body swap??

tip number 1, jack it up 1/2 meter off the ground and do the roof last, because you will be over it by then.

get a double garage and put it in the midde of the double garage - you will need the room to work around it.

do not undertake the rebuild unless you have a good spot to do it.
a car port is no good.

go and get a compressor and an air orbital sander and wiz it back till all unsecure paint is gone - this may be down to bare metal in some cases.

cut the rust out and get some replacement sections.
