Thanksalot, guys, I'm really satisfied with the results. The trick is to be completely naked (high heels are okay), put some lipstick on and dance to "Goodbye Horses" while spraying.

Or you just sand it like there is no tomorrow, the more even the surface the better, put primer on, and then spray
crosswise (use equal spraying moves and equal distances) while constantly checking from different angles. The more coherent the spraying moves, the better the results (it's a little like in Karate Kid). I think that one benefits from the solvents in the air to help relax.
