You are correctt about the brand, Its a 2 in 1 Evo with a 0,2 and 0,4 set up i switch between. I love it, If i somehow wreck this one ill get a new one thats how much i love it. It simple and you can mod it with a lot of different parts available from the dealers.
About the Trigger finger, I do this because if i don't the paint buildup on the edges will be way bigger than the rest of the surface, If you look at a car painter he uses the same technique, This is also a lot more paint efficiant. This helps prefent runs.
Sadly enough the paint is indeed only available in europe, But in the US and around their you have scalefinishers, Ive heard a lot of good things about them aswell. Don't worry about asking questions, Happy to help!
