The one thing a lot of people don¡¯t do is after you have clean your airbrush, don¡¯t just leave it that way, pour some kero into a lid and allow the straw of the airbrush suck some in so you are blowing kero out in a mist, then dunk it back in again and one small squirt and leave the airbrush with the kero in it, thinners is very harmful to O rings by leaving the kero in the gun it keeps the O rings nice and soft, I leave my airbrush this way for 6-7 months of the year because I am away from home, when I next want to use it I just pour some thinners into a lid and start sucking it through the airbrush allow the straw to blow itself clean a few times and it is then ready to start painting again.

Hi Folks,
?
I find the best method of learning how to airbrush, is to teach yourself. Read the theory from magazines or internet etc (ie. paint to be thinned to the consistency of milk etc), and then teach yourself the practical side. See what happens when paint is too thin / too thick, see what happens when the airbrush is too close / too far from the work piece, what happens when the pressure is too high / too low etc, what if the needle in your airbrush is not a good choice for the paint you are using, what happens if your air cap on the airbrush is not sealed properly? I am sure that we all have some old paint sitting in cupboards, which will be perfect for training purposes. I suggest used kitchen containers are good for test work pieces, especially cans from soup or fruit or soft drink etc. Just make sure that they are properly cleaned to the same level of preparation as your model. The weather can also be an important factor in your painting results. Cold damp weather is not good for painting for many paints.
?
My experience has been knowing what not to do, has made me a much better painter, and when things are not going as they should, you need to quickly identify what is wrong. The more times you dis-assemble your airbrush for cleaning, the more comfortable you will get using it. I have seen some first-class paint jobs from modellers with very basic equipment, and I have also seen some disastrous efforts from modellers with very expensive equipment. This all comes back to the users knowledge and skills in operating their equipment.
?
Last piece of advice ¨C painting can be very unforgiving when it goes all wrong. Make sure when you set-up your airbrush for a painting session, do so some test painting first on some scrap material, and have that feeling of confidence, before allowing the airbrush anywhere near the model!

Hi Frank,

I undertook an airbrushing course.? Whilst basic, I would recommend doing one as it may help to de-mystify the tool.

Rod,

We tend to be a bit afraid of cocking up the job at the last stage. I still airbrush with trepidation, but I always think that the blokes who do hot rods and motor cycle tanks started somewhere.

?

Now that is an art form, but outside its 'clan' virtually unrecognised.

Hi Frank,

I was a little flippant.? My intent was to show the previous writers that air brushing is not that frightening.? If in doubt I would recommend Tim Shackleton's airbrushing DVDs.

My steps for brass painting:

1. Lightly grit blast.
2. Lightly prime with an aerosol automotive primer.
3. Spray smoke box with gunmetal aerosol.
4. Spray remainder with desired colour, in my case a dark grey of some sort.
5. Weather as per Tim Shackleton and/or Martyn Welch.
6. I weather over the gunmetal as well as the body.

PS: my little Garratt is a HOn30 unit as used by Victorian Railways NG lines in Australia.

Rod,

There is no such thing as a 'little' Garratt!

If possible lightly grit blast before painting. Even with etch prier the key is much better.

Just go for it. I sprayed the smoke box with a gunmetal aerosol and air brushed the body with floquil grimy black.?? Weathering alah Tim Shackleton, and you have a dirty little Garratt.

Stunning, I find taking an air brush to a beautifully built brass / nickel silver model quite nerve-wracking, which probably explains why I have many fully built but as yet unpainted models!
