I reckon its a good plan to WD-40 all the nuts and bolts a day or so before you disassemble.
It'll make the job a hell of a lot easier.
The other thing is to be really organised. Buy a packet of Glad sandwich bags, the ones with the white label strip and bag and mark EVERYTHING. Get some boxes and put the bagged parts together based on location on the car or some other criteria. Then mark the boxes. If the bits are too big then wrap them in newspaper and mark the outside.
When it comes time to put the car back together this will save you countless hours of frustration looking for bits.
Oh, and if its the first one you've pulled apart take plenty of pictures for reference when you get to putting it all back together.
Good luck, another one saved
