Spray Painting Questions
paul swainson:
Hi Colin, Thanks for that, I have taken a copy and will try out a few thinks at the weekend and report back. A good article for the forum tool box ^^^ Paul.
radio joe:
When I finished reading the article that Colin posted it reminded me why I never use a airbrush, I'm sure the aficionados of airbrushes would disagree but for me there's just too much bother, I only use acrylics these days and with a decent brush and a bit of care you don't even get brush marks, but as they say each to their own.
paul swainson:
I am going to paint one of the STAAG with a brush, the other I will do with the airbrush (if I get it to work) which arrived today. Will them post pictures for you to see. If the quality of the paint work is of a high quality it will enhance the model. So will try both and them make up my mind. I find that there is no difference between cleaning a airbrush to cleaning a paint brush. I just have to spray cleaner through the brush. Any we are off topic with this one. :grin1:

Hi Paul
I have used an airbrush for some years now whenever I can, sometimes I am forced to use a brush but if I can I use my airbrush. I only use Humbrol enamels and I use about 50/50 paint to thinners but it does depend upon the thickness of the paint. Someone said the thinned paint should have the same look as milk. I use about 30 psi pressure. As to acrylics, well I did try them but gave up. I found that no sooner had I started spraying the airbrush nozzle became clogged up. Another point but I expect you have discovered this already - absolutely imperative to keep the airbrush clean, any presence of dried paint and it won't work - I expect that was my problem with acrylics as they dry very fast.

I agree with you, Robin. I use Tamiya acrylics and take thinner until the paint has the consistency of milk.
For the hull I use 2-component car paint. With that paint you have a fixed ratio for airbrushing: 50% hardener and 25% thinner. The result is as the described milk.
Surely you can make a lot of faults using an airbrush. My worst experience was in winter: I thought warm paint would be better and put the can on the central heating. The result was a model which looked like an orange. So I had to put everything into brake fluid an restart from the beginning.
You should also invest into a quality airbrush. I had a very cheap one which was not good at all (it was a copy of a brand product). With a well known brand you normally have no problems.
