for the lazy at heart;
Tin foil is the best masking material ever, and plastic bags. Ofcourse you still need a little tape though.
I did mine in gloss black.
If i were to do it over again i would change a few things.
1) Dont paint it in winter on a -20*C day.
2) Dont strip it to bare metal, just scuffing the factory paint is plenty.
3) Use primer before paint.
4) Use satin instead of gloss.
The gloss turned out pretty good, but its just a preference. I dont like it in bright pictures, because it reflects too much, and distracts your eye from the engine. I painted it black to focus it on the engine.... (see last pic)
