Does anyone have some gunpla they've put together recently, or that they're working on?
Here's an old RS-178 MKII PG kit I assembled recently. Still deciding how I want to detail him, but as my first PG the level of detail and articulation is really cool.
I started out with a basic harbor freight set; definitely would not recommend. The airbrush is siphon feed so IMO it was a pain to clean, and the compressor didn't come with a tank or regulator.
I bought an Iwata Neo CN a while back, which has been pretty fantastic in comparison. Easy to use, easy to clean. I'm still using the HB compressor because I bought a regulator specifically for it, but I'd definitely recommend just getting one with everything. Regulator is important to be able to control your spray pressure, and the tank will store air and keep your compressor from running all the time. Right now in the hotter months I've been worried about it overheating.
Also if you're spraying indoors a spray booth and respirator are a must, otherwise you're going to be breathing in all those paint fumes.
Good luck with your Aerial! She's a great kit, I was really impressed by the engineering and I'd recommend her to anyone.
