Revell enamel paint + Airbrush; Thining enamel paint

I am just starting with my first project,bought a audi r8 model kit from revell and i am confused a little bit about painting the body.
I may sound like a complete beginner,but i truly am and would like to learn more.
I have bought enamel colors and the basic airbrush+air pressured can with it.
Now i saw in this forum that enamel colors need to be thinned with thinner(i have color mix from revell), but i don't know exactly how much is needed in order to paint the body, and how to mix them with thinner.
Any recommendation would be appreciated,as i am really happy to start building the model.

Thanks

It partly depends on what type of airbrush you have. If you have a siphon type where there is a dip tube into the paint, the paint needs to be very thin, otherwise you need a lot of pressure to get the paint flowing, at least 50/50 paint to thinner would be a starting point. Whilst canned propellant is a good way to get started you will find it very expensive, the cans don't last all that long. Also it can be very hit and miss judging how much air there is left in order to clean the airbrush with straight thinner. If you think you might be doing a lot of airbrush work then investing in a compressor will save money after a relatively short while.

One tip when using canned propellant, it will rapidly chill and the pressure will drop after a short while. If you stand the can in a bowl of warm (but not too hot) water it will provide reasonably even air pressure as you spray.

Hello Peebeep,

Thank you very much for this info,as i am a starter, it is very useful to me. Btw i have bought the syphon type of airbrush which has a little tube which is going in the paint can.
That sounds perfect, i will test how it goes tomorrow as i am still waiting for the primer from revell to arrive.
And yes, you are right, the air propellant is not that cheap so if this model comes out nicely then probably i will consider buying some compressor that will save me money on the long run.

Really excited to see what will come out.

Thanks again

Hello user. Can you please state which airbrush brand you have bought and a type name? That would help in telling where to look out for. Instead of buying the canair an old tyre may work as well.

I think you have single action airbrush. So if you press the trigger there will be paint. I take it since you are to asirbrush a car model that will do just fine with single action.

The mix should be about milk like or bit thinner than milk, but not water like.

hope this info is helpfull as well. feel free to ask here ;)

Hello Eric,thanks for your interest in helping with this.. I just checked the box but i do not see a model number or something :( ....Anyway to answer the question, yes the airbrush model is the most basic one from revell,bit plasticky with a glass can on the bottom and a tube going inside for sucking the color. Its a single action one which only has a simple click and there goes the paint :).
I am just wondering about one thing,i have sanded the body today so tomorrow i will apply a spray of primer on that before painting it with the airbrush,so based on this info do you have any points to give so i can be careful on what to look out?

Many thanks :D

Also, another thing that i am concerned is the pressure..The cap where one part of the airbrush goes to the propellant has like pressure adjuster,so i cannot really determine if the airflow is good enough or too strong/weak.
If anyone has experience with that i would appreciate it to be shared before i start messing around with this :)

With the type of airbrush you have - it is a mini spray gun technically, if it has no needle - you will need maximum pressure to get the paint flowing. You also need to get the height of the nozzle relative to the air flow just so in order to start the siphon. It would probably be best to get this setting using water in the jar before attempting to spray with paint. There is some measure of control in the spray pattern by raising or lowering the nozzle, but the amount of control is very limited.

Thanks alot peebeep, yes i will try with water just to see how it will go before putting the paint.
i was looking at the user manual for the airbrush and i saw a picture where it shows the adjustment for the nozzle.Hope it will work :).

Guys, i would like to ask one question regarding painting the small parts for my model car like for example engines,rims and etc.
How do you recommend to paint them,i have those brushes from revell or to spray them over?
I think with a brush would be better as i want the engine to have 2 types of colors on it.
Also the sits and the cockpit requires attention to detail.
What do you think?
Any recommendation will be appreciated

\thanks

I am not a car builder, but do build them as a sidetrackto do something different. The body and chasis that wouldbepossible to airbrush with the oneyou have now. I'm not too sure about the wheels and engine. Prime the chasis and body, and while doing that taketheengine and wheels in the same session. You only have to clean once that way.

After everything is dry and hardend out, you can do the main colour for the chasis and body but do clean the airbrush between colours. Wheels you can brushpaint better unless they are the same colour you used for lets say the body colour and chrome.

Hope this is explains it better for you, feel free to ask more that is what the forum is for! :D

I did not had time to start with coating, but tonight i want to do it.One concern i have though is that after sanding i see some scratches from the sandpaper.i was doing it with 240 grit and after that with a nail polish paper,so i am concerned if i can start applying the primer or should i sand more with some higher grit paper?
I saw some guy on youtube was doing it with a 240 grit and he said his models looks good.
