I always take tons and tons of pics whenever I take anything apart...keep your camera handy and snap a pic every step of the way..that way you will always have something to refer back to. It also helps to keep a roll of scotch tape handy so you can tape each set of screws to each part as you dismantle it..you'd be surprised how many screws there are!! There is a product that I use called PB Blaster..it's to loosen up rusted scews and bearings...you can get it at walmart or an auto store..it works well on rusted scews and rusted up bearings..I would keep it away from any decals..hard to tell from the pics if you have any or not..but it works well on metal parts! Post pics and let us know!
One more thing...if you are serious about the red...you can take the parts to an auto body shop and for very little money they can paint it and clear coat it...it will last a lot longer than a can of spray paint would!
