Air Brush
« on: September 27, 2016, 09:59:39 PM »

Hello all
i tend to use Halfords spray paint for my models as they are big at 5 foot by two foot this is my current project it cost a small fortune in rattle cans so i though about an airbrush but these tend to be small and i have not had much luck in the past with getting the mix of paint right and it ended up a clogged up mess but after watching all the car restoration programs they seem to use much larger versions but these may be too big for model use is there anything between them

I use a mini spray gun for everything but detail work. Generally cheaper than air brush, larger capacity, can spray thicker paint, easier to clean & can turn the fan down very small. Disadvantage is it uses more air & produces more overspray.

I don't know what they specifically are called in your area, but over here, they are called "Detail Guns"....  basically a small version of a classic automotive airbrush, designed so spray "small amounts" of automotive paint.  capable of spraying much more than a standard model airbrush, but not as much as a fullsize airbrush

I wish some one could help new guys to air brushing paint how to mix the paint to get the milky mixture.  I use Humbro Acrylic   small paint tins but can I get the mixture correct. Could some one who does regularly help with say weighting the amount of paint and then the amount of thinners to get the milky mix.  Would be a great help.

I think the reason its not easy is because each brand, and each type (acrylic vs lacquer, Humbrol vs Pactra) all use different ratios, and some company's recommendations work well, while others have to be tested and altered.  in addition to that, different airbrushes with different needles require different viscosities.


basically, what i am saying is its a black art to get YOUR paint to flow well through YOUR airbrush, and practice is the best answer.
