Practice makes perfect. I paint my own chassis now and I've had to learn a couple of things along the way ...the hard way. When they say, what doesn't kill you, makes you stronger is very true. You can live from horrible experiences and hopefully it'll teach you to not make them again. To make things easier, you may want to go through some of MNPCtech's guides. They offer a lot of insight and ofc there is also a fella known as Hanoverfist on OCN who is killer with paint skillz.
