QUOTE: a) Do I need to thin always the paint with thinner? Is a recomendation? |

If you are hand brushing you probably will not need to thin the paint. If you are using an airbrush you will need to thin it enough so that it will spray at the pressure you are using and give good coverage. How thin will depend on the pressure you use and your airbrush. 3:1 (paint:thinner) is usually a good place to start but you may need to thin it more.
QUOTE: b) Aproximatelly how much paint series normally I need to apply to get the final colour? |

Again, this depends on whether you are hand painting or using an airbrush. It will also depend on the paint you are using and the color of the paint. Yellow, for example, is very difficult to get to cover properly. Use light coats, and then enough to get a complete coverage so that you cannot see through it.
QUOTE: c) Do I need to wait always for the full dry before apply a new cape? |

Yes! If the paint is not allowed to cure then adding more coats over it will simply cause it to take longer to cure. As paint cures it shrinks slightly as the thinner evaporates. Adding additional coats before the lower layers are completely cured can lead to paint cracking or the paint pulling up when using masking tape.
QUOTE: d) How I avoid those vessels when Im painting with brush? Is normal to get some vessels at the end? |

If you are hand brushing, I am not sure since I do not hand brush very much. If you are airbrushing, keep your hand moving any time you are spraying paint. When you press the trigger your hand should already be moving. When you let up on the trigger your hand should still be moving. If you stop your hand moving you will get a spot there.
