I’ve chosen the tread title „Maintenance kit” for a brief review you’re going to read for the reason the kit actuaaly is not only for cleaning the airbrush. The kit is from Tamiya. You can see on the photos how it comes. The kit includes: Wranch for nozzle removal (clone of those your Japanese airbrushes come with) Nozzle sealant (red one) High viscosity grease (transparent) Two cleaning brushes Instruction booklet I was interested in nozzle sealant and in one of the threads forum member pointed out this kit. Now, having tried one I can leave some feedback. There shall be not much talk about the wranch here. You all know what it’s used for. Nozzle sealant. It’s the main reason I’ve bought this kit, as other things I had and used before trying the set. All threaded nozzle AB models of Iwata and Olympos (I could presume other Japanese ABs either) when come new, have some red substance on the nozzle threads. I always wondered what that was. Now I know. Viscosity of the sealant is just great for applying and sealing. Using the sealant you will not have bubling in the cup for the reason of air coming through the nozzle threads and using this you would apply less pressure to seal the nozzle as you usually do. From the first use I liked it and going to use every time the nozzle is unscrewed. Just for this sealant the kit is worth buying for me, but there are other things included. High viscosity grease. As seen from the insruction scans, grease is used for greasing moving parts and sealing air nozzles (caps). I’d say that Japanese Abs come with some kind higher viscosity sealant on the air caps. Before buying the kit I experemented with different materials to get the results I needed, so I already had similar stuff (will say a few words later). Cleaning brushes. They’re used for cleaning paint passages of an AB. From the appearance they look OK and similar to those I’ve used before. Be ready to get that one with aluminum handle bent, as the handle is made of very thin aluminum tube, good enoght to clean the AB, but not that good for international shipping in buble warp envelope (as it came in). I would recommend this kit for any airbrusher that uses threaded nozzle ABs. On further photos you can see what I’ve used before buying the kit. As I’ve already said, I haven’t found good nozzle sealant as original Iwatas come with on the nozzle threads. I found other ways for the sealing, but they woudn’t suit me. For sealing the air caps I found that some car break system greases are of high viscosity and can be used for sealing. You can see on the photos Liqui Moly red and light blue greases. They are of equal viscosity as Tamiya’s kit grease. I like transparent red one as it’s not that that visible on the AB as light blue (opaque) is. And light blue has some ingredient in it that’s not good for the skin. For greasing the mechanism I use lithyum grease. It sticks to plated parts just great, greases just as expected and stays in the place I put it. You can see on macro photo of it, that it keeps it’s shape inside the storage cup for months after I picked up some with the needle tip to gease the parts. The brushes I used for cleaning the paint passages and AB parts are interdental brushes and artist’s brushes. Both work great with urethatnes. Artist’s brushes are the cheapest nylon ones, there’s no problems with them. You can see how kit's brushes are compared to my custom mead brushes and interdental brushes.
