winter prep

i have a jeep YJ and this wil be my first winter with her. since winter is coming fast i need to get her fully preped as best i can, dopes anyone have any suggestions ideas or tips on what to do, how do do it etc...

i plan on cleaning the frame with wire brushed and stuff to get some of the flaky rust off to have it properly rust proofed. should i use a pressure washer to clean under the car( frame/ underbody etc...???)

please leave your ideas and such they are greatly appreciated.
thanks!

remove main rust... ok its good
i'd say tar it up or even better use POR-15
then rust proof the main areas
get a good check up done, battery strenth, u joints, steering and so on.
you should be good

kool thanks for the advice
