well i love doing it and the more challenging it is the better i do. i done a gas tank with skulls and real like flames and it took me a while but in the end it all came out good. i have a iwata gravity one and a siphon one and love the siphon one so much better. the gravity one can do some sick thin lines and is great for detail. i also have a cheap harbor freight one, and to tell you the truth its a great little cheap gun. i usually do my colors with that. but love it and im always practicing, like on the weekends like 13 hours since we are slow as hell at work..haha
