Fill your inner frame, rockers and every where else the sun doesn't shine with some nice gear oil. Drive around for a while and then go park in someone elses parking lot. Just don't tell Al Gore. Repeat every year. Oh yeah and develop some oil leaks and don't fix 'em. Another less severe option is to wash it with a cap full of kero. in your bucket every time. Remember Subarus rust from the inside out so you need to treat the inside not the outside.
