Sorry to get all serious on you, but when you're dealing with carcinogenic liquids (which pretty much every type of model paint, primer, thinner, etc. is), you really don't want to take that stuff lightly. A family member of mine recently beat lung cancer under "best possible" conditions, and even that was scary as hell for us and extremely painful for her. Even if you're a healthy person and they notice the tumor as soon as it starts to grow, treat you without needing chemotherapy, and get it all out in one go, you'll be bedridden, in incredible pain, for months afterward--and you could end up losing 15% of your lung capacity in the process.
Do not fuck with cancer. Respirators are less than $20 on Amazon.
So pva is actually just elmer's white school glue, but there are varying degrees of it. Mod podge, for example, is a different type of PVA that has dries harder. Any of them will do, honestly.
Amazon has a lot of the stuff for fairly cheap, including masks (I highly recommend this one [link])
You could probably get by with a 1K (one part) clear, but the spraymax 2K will definitely be durable. You might want to practice on a few junk parts first if you don’t have a lot of experience. It will take more work to remove blemishes or orange peel once cured. You should wear a respirator when spraying that kind of clear. Make sure you clean the keys very well. Soap and water should work and a mild solvent (test first) like isopropyl alcohol or wax and grease remover. You’ll know they’re clean when water “sheets out” over the surface.
I just ordered some P95 masks from Amazon myself since N95s are sold out everywhere, they should be here in a week. Just not sure how they compare to N95s.
My friend printed ABS all day long our freshman year, we got used to it pretty quickly (though it is still toxic though so...)
With ABS's warping issues keeping a window open is not advised, but if youre in a single and dont have to worry about roommates you can always get a respirator and just wear it while you print.
I print ASA a lot next to my desk and if I start to smell it too much I toss on the respirator, works great.
Edit: tossing a cardboard box over your printer will help with warping and also help with fumes more than you'd think it would.
I use rattle can primers sometimes with my hobby paint booth. It pushes air up a 4" dryer hose to the outside of the house. The vent fan motor is not in-line with the air flow, the fan being a "squirrel cage" type. So zero risk, but it was a joint decision with my SO.
For inline, I'd suspect there is too little flammable vapor for too short a time as u/SigmaHyperion says.
I do recommend strongly a proper respirator mask when using rattle cans. I skipped it first time and the fan just did not exhaust the fumes fast enough.
Making micarta from blue jeans or canvas is very "safe" in the spectrum of safe. I have to say though, it never hurts to go totally overboard with like a P95 respirator setup, and just like wear it all the time (except for forging lol).
Honestly don't stress what respirator to get too much.
This 18$ 3m respirator is all you'll need for years if you're just modeling. Getting anything of a higher tier is just overkill.
I'm a bit paranoid due to family history of lung disease, but I wear a paint mask whenever I spray anything (rattle can, airbrush, etc.). I also wear gloves, mostly for ease of clean-up and eye protection if not using my spray booth.
I would just order a new mask. 3M makes a decently cheap one and the bags resealable so it doesn't get wore out by just sitting around.

I don't think an airbrush would work very well. The spray pattern is typically very small and can only spray thinned paints. Try and find an automotive paint store and get automotive paint and a 2K clear (both come in aerosol cans). You'll need a clean place to spray and a respirator .
I'm sure that airbrush would be fine for learning and while you save up for something else. I got to the point that cost of rattle cans was going to add up to me buying an airbrush any way.
I only use Alclad II primers, so i have no input on Vallejo.
You don't need to thin it, Alclad paints/primers are all airbrush ready. Yes, they're lacquer based. I've found that Alclad's AB cleaner works best, I tried Tamiya Lacquer thinner but it just didn't seem strong enough to clean as nicely.
I wear this mask.
I just run mine down the drain with some dish soap, not sure if it is the correct way or not. I would just soak it up into paper towels and toss them, but there is always an innate fire risk with that route (any chemical rags in trash is a risk).
Thanks for the reply.
I was thinking about grabbing this respirator
As for cans of paint, for spraying like Nadalee, which cans should i purchase?
I'm originally from the Chico area, and the Camp Fire hit my social circle pretty hard. I went up to help out in the make-shift camps/shelters being set up, dropping off and passing out supplies. The smoke was so bad that in the middle of the day, there was very little sunlight.
Some tips I've learned:
1. It's all about PM2.5 particles
Last year, people were sharing masks and filters that weren't sufficient for the true hazards in the air, the PM2.5 particles. These can get into your lungs and blood stream and wreck havoc long-term. So you need filters that cover these. Always look for that (and P95/N95 ratings on masks), and don't fall for some of the trendy-looking-but-otherwise-useless masks some people share around the Internet, or think that a surgical mask is going to do any good.
2. Treat yourself to quality personal air filters and goggles
Buy a good reusable N95/P95 respirator. The little paper-like masks are good in a pinch, but you're going to find that they're not that comfortable to breathe in, and if you wear glasses, you're going to fog them up.
I recommend the 3M 07193 Dual Cartridge Respirator. This is technically disposable (you can get replacement particular filters, but the carbon filter can't be replaced). However, it will actually last you a fairly long time. They're affordable and you're going to feel like you can actually breathe comfortably, even in heavy smoke, especially compared to those little disposable masks. I have a couple of these so that I can share with those around me.
I've since picked up the 3M 65021HA1-C Respirator, which is P100 (better than a P95/N95, adding resistance to solids and liquids containing oil) and has replacement organic vapor/particulate filter cartridges.
Along with these, some good safety goggles will help keep the smoke out of your eyes. I find these Dewalt DPG82-11 goggles to be pretty comfortable, even with glasses (though they may be a difficult fit for larger glasses).
3. Buy a new, quality home air filter
You have whole-house air filters in your home/apartment, and they probably do nothing for smoke. Most air filters people buy help with allergens only. So do yourself a favor and buy some air filters before they're out of stock everywhere. Something along the lines of the 3M Filtrete MPR 1900 filters or, even better, the MPR 2200 filters (make sure you get the right size for your place, but I think 14x24x1 is pretty standard?).
MPR 1900 ratings are a minimum requirement here. There's a chart on that Amazon link in the product pictures that shows you what filters you need based on what you're trying to filter. Look for the PM 2.5 Air Pollution.
Note that the higher the filter, the more your heating system will have to work, so just be aware of that.
4. Buy good portable air purifiers for the home
Along with the whole-house filter, you're going to want something you can put by the door or the windows (by the way, close those windows). I have a few of the Vornado AC350 air purifiers (one for Palo Alto, a couple for my place in Chico). They're not cheap (and right now they're more expensive than they were -- I paid $99 -- so shop around).
You'll also want replacement filters. In a pinch, you can wash the old filters, but I don't that that's a good long-term solution.
5. Car filters!
If the smoke gets really bad, and you're driving around in it a lot, your car's cabin filter is going to capture a lot of that smoke, and that's going to start working its way back into your cabin. You might want to consider getting your cabin filter replaced.
I know this can be done manually, just buy one online, take out the old, replace it. I had the dealership do this for me in Chico, but they were doing this for free for everybody, so... Lucked out there.
6. Avoid being outside as much as you can
If you don't have to go anywhere, don't. It's just not worth exposing yourself. You don't know what's in that smoke, or how well protected you are. Just prepare, buy food for the home, get the filters, and minimize how often you leave the house. This isn't always practical, and if you do have to leave, make sure you and your family are using quality air filters.
Check the air quality on a site like PurpleAir. Don't rely exclusively on your phone's Weather app. You want to use something that's tracking many sensors in an area, not just one or two official sensors.
Edit: Added a link to the PurpleAir air quality map.
Edit 2: Thanks for my first-ever Gold, kind stranger! That was very nice of you.
I’m happy with this one from 3M, but I also don’t have a beard.

Are P95 masks an ok alternative to N95? I ordered a few p95s from Amazon just not sure how effective they'll be in case shit hits the fan.
Nothing fancy, really. Mine is similar to this one. The refill. And the mask
They are masks. Just special-er masks:[link]
I've never done it, so make sure you verify yourself. It appears a half mask organic respirator is sufficient.
3M masks are great.
Here's the one that I use.
Honestly? I had no idea. I have one of these, would it be appropriate, or should I get something else?
That one is pretty good for dust. If you have a beard efficiency is greatly reduced - but that is true for any type of mask.
Respriators offer 2 levels of filtration. Dust, and organic vapor (chemical). The dust filters are like what you see on the amazon listing. The organic vapor filters are charcoal or other types of carbon filters. It's nice having a mask you can use one or the other because the organic vapor cartridges are really cumbersome and not needed for general dust.
For EVA foam, it sounds like you want the organic filters. I believe only the "nuisance level" filters are available for this model. I use this one when spraying finishes. The organic vapor cartridges do a great job.
If you deal with organic vapors, don't use a regular dust mask. You'll basically be huffing the stuff. This is basically the dust mask version of the respirator you linked to. It provides some low level organic vapor filtering.
I got you.
Yeah I wasn't planning on putting it over the existing one.
So even this thing isn't good enough for it?
You sure could, but are your lungs cheaper than 20 bucks?
Don't necessarily need eye protection more or less the nose+mouth.
Maybe something like this-
