Needle Size?.

Go any lower, and you will have problems with blockages with paint drying and jamming at the end

Been using Vallejo Aiirbrush Flow Improver through an Iwata .2 with Vallejo Model Air and it works well. I use this for detail work and had lots of problems with drying to early but with the Flow Improver it is a revelation.

Not really used Vallejo acrylics. I have used them a few times, including their primer, but steered clear of them once they ruined my model. Different people have different choices... Anyway, I don't think Vallejo products are compatible with alcohol based acrylics.

Finally Using my New H&S Evolution with a .2 needle, & thinning the paint a bit more & using the flow improver ive managed to successfully spray the body of the escort rally car im building without any blockages ..


Plenty of runs but no blockages.. :D :D.. so now looking forward to improve my spraying skills..

Actually John Tamiya Acrylic Paints are made from water-soluble acrylic resins (Tamiya description). Vallejo flow improver works perfectly with Tamiya. Infact it integrates with Tamiya paint more easily than Vallejo.

Also add that water is compatible with alcohol.


How do I know that ? Cause I saw a host of French pensioners having their lunch. They were accompanied by a number of bottles of red wine. I was surprised to see them dilute their wine about 75/25water.

It also says that they're excellent for brush painting - 1000s of modellers would beg to disagree!

Patrick are you sure it is actually exactly 1000. :rolleyes:

PS there are 1001 who swear by it for brush painting. :D

Sorry Laurie, I used Revell Aqua Colour paint, & Revell Aqua Color Mix Thinners. With 2 drops of Vallejo flow improver. .

As long as it works John and what ever you get on with. That is the main criteria. If by chance you do use Vallejo Model Air you do not need thinners with the Flow Improver. Revell is thicker than the V.Model Air.

I knew there was a reason why I decided on a paint brush against an airbrush. :rolleyes:

Keith once you start airbrushing producing good finishes you will toss the hand brush out of the window. With an airbrush you can produce finishes and weathering shading which cannot be achieved.


Just take a look at this one posted today. http://www.scale-models.co.uk/threads/a-7d-72-0235-hasegawa-1-48.30562/#post-266198. No chance with hand brushing.

Yes, I can see why you like the ab but my goodness it sounds so complicated. Air pressure, needle size, trigger pressure, retarders, flow improvers, then you need a spray booth, extractor fan, face masks etc. All I need is a brush. The models that require fancy blending in the paintwork I will handle by not buying them.

Air pressure never changes (the gauge veers around the 35-40 psi range), whichever airbrush I'm using and whatever I'm spraying

I find it amusing how Vallejo say that their Modelair range can go straight into the airbrush... Not really. It still has to be thinned. However, this is a good thing, as you get more out of the bottle.

Is this man you John or the one in the picture or both. The picture being the picture of the man painting not the young ladies picture.


Of further interest is that originally a photograph he is working on. I just cannot work that out.


Also the stick is he using that as a rest rather like an old type signwriter. I use similar things, when using brushes, to steady my hand. Fortunately that even at my advanced age the hand is steady but a stick or something to rest the arm makes a lot of difference. Even small items i rest against something to give a rock baase.

I use a 0.35mm needle and have no problem spraying Modelair direct from the bottle, I normally spray around 20-25psi and very rarely have an issue with tip drying.
