BillyBob,
How far away from a spray car wash are you? I would spray on some degreaser...OK...several coats over a weeks time, put that thing on a car dolly and tow it to the car wash.
I did it with mine. It helped out. Best part was all that stinky old grease was gone. Before you hit the car wash, scrape/brush the big stuff off so you don't wash all that gunk down the drain. Once clean, the old beast will be much more pleasant to work on.
If you are miles from a car wash, never mind.
