haha yea hard indeed, very detailed. need lots of determination
to keep going on, which i lack at times, that's why been dragging
it for quite sometime 
but very satisfying
indeed when i complete each & every phase of it 
well for spray painting of the exterior, there has to be a layer of
primer first. primer is a white 'paint' that allows your colour
coating to stick well to the surface. and, first thing first before
the priming, you gotta soap wash the parts first and dry
them.
after the colour coating (which alone involves a lot of pointers),
there are also works for polishing & waxing.
if you're talking about the other parts of the car, i.e. engine
parts and interior, you can either brush paint or air brush.
beginners go for air brush, using enamel or acrylic paint. air
brushing requires some monetary investment and skills, and is more
for the seasoned modellers.
