I notice in reading thru FSM (no I don’t just look at the pictures) that quite a lot of you guys , and gals, use acrylics rather than enamels or other types of paint. Being a real rookie with an airbrush I was wondering which gives the best result in terms of ease of useand clean-up. [?]
Also, can you mix different paint types on the same model, or should you stay with one type at a time?[8D]
“Always remember, your weapon was made by the lowest bidder.”
I use all sorts of paints. You can mix them on the model but you should follow this order to avoid trouble.
Thanks for the info. I’m still re-learning the modeling game after a really long lay-off, andI’m learning to use an airbrush for the 1st time. All help and advice is greatly appreciated.
In terms of ease of use and clean-up acrylics are far superior to enamels. Acrylics wash up with water or alcohol. They don’t create nasty fumes and can be wiped clean off the model if you make a mistake with a alcohol-soaked q-tip.

Oops, don’t know for sure how I did that. Sorry.[#wstupid]
Learning to airbrush? I spent my first day (oh so many years ago) with a sheet of poster board drawing circles and squiggly lines before working on some plastic.
Remember though that acrylics are more dangerous to breathe than are enamels, so don’t let the “nasty fumes” fool you. [;)]

I didn’t know that!..and here I thought I was doing myself a favor by trying to convert to acrylics…Maybe I’ll just go back to my trusty old nasty smellin’ enamels.
Mike, you continue to be a wealth of information!
Let me reiterate that none of these paints are healthy to breathe, but acrylics are plastic based and as such they can coat your lungs if you are exposed to them over the years. With the amount of paint we use for models there is probably not much chance of harm but it is always best to ventilate as much as possible with any paint mediums.
Mike
Additionally acrylics can be toxic free and odourless, a strong point for you health.
…alllllllllllllrighty then…I’m so confused…[:)]
What do you mean by toxic free? Any plastic based paint that is inhaled would not be considered toxic free.
Where is our resident chemist on this forum? [:D]
Mike
ALL materials are toxic, it just depends on the dose received.
From what I can tell, acrylics should be relatively safer than enamels, considering the kinds, types and characteristics (e.g.,volatility, concentrations, etc.) of the base solvents. Regardless of the type of paints used, precautions such as respirators, opening windows, turning on fans, and using a spray booth should be employed during painting sessions.
Based on what little I know about particle dynamics, I don’t think that there should be any concern about acrylics coating the lungs over time. Solvent vapor inhalation is the primary concern, IMHO.
I think there are some “non-toxic” acrylic craft paints, but that is based upon the primary intent of use (i.e. brushing, where the primary hazard would be skin contact and ingestion–important considerations for childrens’ paints). In addition, the removal of heavy metals like cadmium, chromium and lead also lend a hand toward a reduced toxicity paint, but I think any time you start spraying, you increase the risk of potential toxicity through solvent vapor inhalation by a couple orders of magnitude.

Thanks for the answer Gip. It was you I was alluding to when I said, “resident chemist” by the way. [;)]
Are you a chemist?
I will have to shoot an email off to my friend who would know the answer to this question of toxicity. He has been in the airbrush game a long time and has even helped design airbrushes such as the Vega 2000.
Mike
If it doesn’t smell and make you woozy-I don’t use it!!
HUH?!
Gip Winecoff
I guess he means he only likes solvent-based paints. [;)]
One thing that is an advantage about both acrylics and Model Master paints is the extremely fast drying times. When a paint dries that fast it is not as toxic if inhaled from what I have been told, because the paint is dry and is similar to inhaling dust.
Mike
The paints that are really bad are urethane toners like they use to airbrush automotive murals, etc. These paints are Isocyanates and not only enter the body through the lungs and skin, but also through the eyes! [:0]
That is why they use fresh air helmets and full-body suits in the paint booths for these.
At least we don’t use them for modelling, or at least most of us don’t. [;)]
Mike
The reason full body suits and airline respirators are worn when working with paints containing isocyanate monomers is the fact that these paints are sensitizers. Once sensitized to the product, the next exposure can produce a severe sensitization reaction in the body similar to the symptoms associated with asthma. Skin and eye contact, as well as inhalation, can trigger a response to the product. Over the years, manufacturers have made improvements in their polyurethanes by reducing the amount of free airborne isocyanate monomer, but the overall sensitization hazard still remains and warrants continued protection, including medical monitoring.
