Homemade anhydrus amonia

Hi!
TL;DR: My airbrush is spitting, changed everything, is it the gun itself?
I've read the pinned post and some similar threads and couldn't find the answer, so here it goes:
I have a starter minicompressor airbrush kit. Have had it for a year and learned a lot. I watched ton of videos and have found my way thru paint diluting and proper gun cleaning. I prime 3d prints and paint them mostly with crescent success rate, but some issue is permanent.
The thing is, my airbrush spits a lot.
I dissassemble it and clean it, it seems to work but when the lever is going forward to a closed position, it spits paint. It seems to work ok for the first couple of minutes but when I think that I finally solved it, ptschh!
It happens with any level of paint dilution, even with a highly watered down . I dilute craft paints or Vallejo primer or Game color with distilled water or a homemade thinner with Distilled water, IPA, amonia free window washer and glicerine.
I recently connected my cheap chinese gun to a high end dental compressor and used it at 30 PSI and I found that it's a little more efficient, but the portable compressor is not that bad, it outputs something around 22-25 PSI, judging by the feel and noise. The spitting was not removed by a higher pressure.
I have replaced the nozzle and the needle. The spit happens with the new 0.3 mm and with the 0.5 mm needle/nozzle as well. No luck either.
This is quite frustrating.
Help me Obi-Wan Kenobi, you are my only hope!
Thanks for reading! With love, Thomar.

Here we go
Did you guys know about smiling salts they're really good to make you more focused and really wakes you up from anything. They actually use it wake up people that fainted
So what you need to make smelling salts:
You need a jar of piss, yeah simple as that then you're going to storage you jar of piss really sealed up and wait it takes while to transform piss into amonia you can accelerate the process if you have a vacuum machine is like making pickles after all
Then you're going to add ethanol you can use 70% alcohol but I advise you to isopropyl alcohol since it's more pure. You're going to put the alcohol into the jar of piss and stir it not shake it just stir it really slowly.
Smell it if it's too strong you need to add water, distilled water might be too strong but for me it works pretty.
DO NOT LET THE JAR OPENED! you can take a piece cotton wash it with the solution and put it on a can with a lid so you can take it anywhere you go
I did not smelled right now my homemade version it's way stronger it lasts 7 hours

I've been cycling my tank for about a month now, using Seachem Stability and fish food (though I started with a dose of pure amonia). Right now I've got amonia at 8, nitrites at 4, and nitrates at 40 so I'm getting pretty close but still nowhere near ready for a fish.
Of course I'm impatient though and couldn't help torturing myself by visiting the bettas when I picked up dog food. I made the mistake of making eye contact with one super cute little dude who was laying at the bottom of his cup, checked his date and saw that he'd been there for a couple weeks already. Still, I steadfastly told myself to be patient and left the store without a fish. Then on Monday I had to go back for cat litter and I saw that he was still there, still laying at the bottom of his cup but otherwise looking healthy, and he swam right to the top when I put my hand near the cup. I didn't have the option of buying him that time, I had a doctor's appointment to get to, and I've managed not to go back. My numbers are way too high and I don't want to risk killing him.
But tomorrow I have to pick up more dog food. And my partner's Dad happened to buy me a bottle of Seachem Prime when I first got started. If he's still there (he may very well not be) would it be crueler for me to leave him at the store or to bring him home and try to finish my cycle with him in the tank? If the best option is to bring him home, then what can I do tonight and tomorrow morning to make the aquarium as safe as possible.
I mentioned some of these before, but just to make it more organized my parameters are currently:
A: 8 Ni: 4 Na: 40 pH: 6.4
In case it makes any difference i have water lettuce, willow moss, and water Sprite in the tank. My filter is a homemade bio-filter on an airpump.
Edit: ok, I'm convinced. Luckily my partner has an empty 3 gallon she was planning on using for plants. If he's still there tomorrow I'll bring him home with a moss ball and and a spare heater. If so I'll definitely post a pic :D

How do you clean vomit off of a matress. My friend got too drunk and puked all over it. My parents come back in around 15 hours. I'm cleaning the blankets, pillows... but i have no idea how to clean the matress. I did some searching and most of them require "homemade amonia" and shit like that. I just wanna clean and take the smell awayy. If you could help i'd be super greatfull.

Well, I have been wondering... Imagine you can't get your hands on neither pistol nor rifle powders (because some retarded law got in effect, because people bought off all the stocks in some grand-scale buyout... think about something) and also factory loaded ammo is unreachable (law... buy-out... etc. etc.). However charcoal, ammonia and sulfur are still available. That along with shotgun powders. You manage to make your own primers that (miraculously) work and find the brass (you make it or whatever).
And you desperately need something to defend yourself - and what's better than a gun? Keep in mind, we're in an urban environment.
Now, I know it's downright stupid to stuff powder in cases not meant to be used with that powder, but the question still remains : what could you load with shotgun powder while still being relatively safe? Also, while home-brewed black powder (the reason I mentioned charcoal, amonia and sulfur is that, while you can make black-powder from it, the resulting product is half as dense as factory powders) is less effective than factory, is there any "autoloader" that can cycle relatively underpowered, homemade-black-powder loads? I'm betting on a modified 1911, with some modifications, because the .45 ACP isn't a high-pressure round to begin with.
Also, I'm pretty new to the reloading world so... Take it easy. But I won't ever load anything with a powder that's not supposed for it - I'm just asking. And I don't want to blow up any guns and/or amputate any limps.
