Ummm, why do I feel I'm all of a sudden not one of the cool kids...
We can be uncool together Mark, I don't have one either - but then everyone knows my approach to colour. Can you say Wing It? Lol. We'll make our own cool club.
Anyhoo, back to the plot. Hi Samsaquanch, welcome from a fellow Brit residing in the Motherland. Welcome to the world of airbrushing, the most fun with a gun you can have (I'm a rebel, I call mine a gun. Well sometimes I call it my dearly beloved - other times it's nothing but a mother funsting flying trucking swank stain - I'm sure you can pick the bones out of that
) - with your clothes on anyway. Other times as you can probably tell, it the most frustrating thing - ever. But usually that all evens out after a while and you get to grips with things. But don't waste the brush by throwing it out of a window. At least tie some string to it, so that you can reel it back in and have another go, harpoon style. You might catch an annoying neighbour - or a passing old lady. Just make sure none of them are inflatable. You don't want that whizzing around the room, and it could be hard to explain to the wife.
Anyway get some paint through those brushes, and enjoy. Then show what you did here. Good, bad or whatever, no trolls only friendly and constructive advice. And when people can see what you're doing, it could save you a ton of time and experimenting. Or you can get a thumbs up and know you're on the right track.
If you do want to upgrade, take a look at the Iwata hp-cs eclipse. It's a lot of brush for the money. An all rounder so pretty much good for everything except large coverage. You can get those with discount in hobby lobby too. While good for detail, the slightly larger nozzle is a bit more forgiving of paint reduction compared to dedicated detail brushes, and in airbrushing terms, is pretty much bulletproof. Less fiddly parts, so easier to maintain too, and the drop in nozzle makes life much easier, with no worries about snapping threads or having to seal with wax etc. As for paint I am a fan of the Wicked mentioned above, as it is good for practically any surface, and I like to mix things up, but it can take a bit of getting used to, and you need to use the branded reducer to get the best from it. But it's well worth it as it has many other great properties as well as reducing, and it is also a good cleaner.
But I suppose before we start bombarding you with advice, we ought to know what kind of stuff you are hoping to paint, and on what surface, and the sizes you're likely to prefer etc, to make sure we are steering you right.
By the way stop picking on Hello for being short. We don't want any of that size-ist stuff on here. Just because it has small word syndrome, and probably starts lots of fights in the pub to make up for it, we can't be putting it down. Anyway at least its better than "Hi"
