As you are dismantling keep a list of the parts you need to replace. People usually forget about all the seals, fasteners, etc. The media blaster will not remove seam sealer, asphalt insulation, etc so you'll have to grind that off if you choose.
And ditto - Plan, Plan, Plan. A simple timeline with money being spent will help you realize how long it will take and when the money is needed.
Have fun!
