Reddit reviews Master Airbrush 5 Piece Mini Cleaning Brush Set Kit, Clean Airbrush, Paint Spray Gun, Nozzle Tip, Tattoo Tube, 3.5 inch Nylon Precision Brush kit

Indeed! Came here to say this.

For what it's worth, I actually have the same Air Compressor, and while it basically works right out of the box (I haven't had to empty the water-catch yet), I will say: be careful of overheating. I'm not sure if it's just mine being defective or what, but I worry about it's lifetime if I'm spraying for long periods of time. They get especially hot because they are oil-less motors (which are good things for precision work -- less contamination). I keep the pressure at 20-40 psi, depending on the fluidity and area I'm working on.

Also, though it's mentioned in neutronicus's link, I urge you to buy these things: small pipe-cleaners (nylon most likely, you can get them at pipe shops or Harbor Freight, and get ones with varying bristle sizes)[EDIT]These ones -- comments indicate others disagree, but it's a cheap solution, and it's worked for me., simple green and strong q-tips for cleaning the airbrush, and Windex or a comparable solution to dilute the paints you spray with (some people just use isopropyl alcohol and some just use water, I've only tried Windex).

And finally! Clean your airbrush after every use! It's odd at first, but I've come to find it as a relaxing task after airbrushing.

You typically do not want to take apart an airbrush too often because eventually those little threads on the parts (any parts) will get to where they wont thread back and parts that seal will stop making good seals.

That being said, I have an Iwata CR and I still will break it down completely every so often and give it a good cleaning, typically not the tip unless there is some bizarre issue I cannot resolve. Taking it off hasn’t made it ‘stop’ working before unless you do not get it back on correctly; however, it is not something I normally take off to clean.

If it is gunked up with acrylics, I would suggest taking it off and soaking it in some paint thinner - specifically something formulated for acrylic.

Also, if you haven’t already, get you a cheap set of airbrush brushes:

There are numerous Youtube videos showing how to use them as well. After cleaning your airbush you can use these and always get a ton of gunk out. I am not recommending this specific brand BTW. You can find these anywhere, even Harbor Freight for probably half price.

Edit: Couple other things I would like to add:

Make sure your paint is adequately thinned (always use Airbrush flow improver to thin acrylics).

Other thing, keep q-tips handy. If you see some build up on the tip of the nozzle after some spraying it is easy and more effective to use a wet q-tip in some thinner/alcohol/etc to quickly clean off any buildup and safer than your finger.

Some Compressor + Airbrush sets are good (like those from Pasche or Iwata) but it's all relative to your needs (as a good brush might not be good for Gunpla due to the scale) and what is offered.

There's actually a very good deal going on right now, as you can get a Paasche TG-3F with Compressor and all your needed accessories + Prime shipping (or free Super Saver shipping.)

With this set you have all you need to functionally airbrush but you'll also want to pick up some needed "accessories" for you.

• Respirator, at least a half mask - Local Hardware Store for best options
  
• P100 Filters - same as above
  
• Alligator Clips on Sticks - you can pick them up at Hardware or Hobby Stores locally as well
  
• Foam Block to put the skewers into and hold up the parts while you paint. Local hobby store, or if you have the packaging material used to ship heavy electronics like TVs that would work as well.
  
• Spray Booth, if you plan to spray inside at least http://www.amazon.com/dp/B00B2TESUQ/
  
• Airbrush Lube, Iwata SuperLube or Badger Needle Juice
  
• Cleaning Brushes, just part of your more in depth cleaning routine that you'll need to do. http://www.amazon.com/dp/B001N3IX3Y
  
  
  You will also want to pick up some glass jars (for storing & mixing paints) as well as some plastic pipes for more accurate paint measurements (makes the jars less messy as well.)
  
  
  I highly suggest getting an easy to clean brand of paint like Vallejo Air to start with, so you can learn with less trouble as Vallejo can be cleaned up in an instant with Windex or water.
