Airbrush reccomendation
« on: Tue Sep, 05, 2017, 01:43:PM »
Back in the hobby after a 30+year hiatus.  Trying to get the hang of airbrushing Vallejo acrylics and have determined that  most of the difficulties I am encountering are coming from my POS harbor freight airbrush.
In the market for a new airbrush. Back in the day I had a  Paasche H and had got excellent results using enamels.  Considering buying one.  But, is a gravity feed model a better choice with acrylics?

I use my Paasche Talon for everything  ,, including larger mixed media on canvass etc .
Most of the problems with spraying Vallejo and acrylics in general is tip-dry .
Acrylics dry quite fast and clog the tip  --  using the proper AB thinner is absolutely a must .

Others here will no doubt recommend the Harder & Steenbeck airbrushes or of course Badger .
AB's are like any other hand-tool  ,  lot of personal subjectives in play .

BTW   -- my experience with Vallejo is you need to ensure they are properly mixed   -- with a stirrer or by adding some mixing balls into the bottle to ensure enough agitation .
Personally  , I never mix coating directly in the cup  I always do it in a small , separate container  -- even though cup-mixing is always demonstrated by almost everyone .

I am struggling with tip drying.  I am using Vallejo airbrush thinner and have tried increasing the ratio of thinner/paint drops to as much as 4:10.  The paint then gets too watery/runny.  This is when applying Vallejo primer.  I'll try the mixing in the bottle; you are one of many who recommend this.
  The talon looks like a very reasonably priced airbrush and has stellar reviews.  I can't bring myself to part with the kind of cash they are asking for Harder and Steenbeck.

You can add retarder  ,, I rarely use it though .
I usually just stop and pull the air-cap and clean the tip off   -- quick fix .
For me  , Vallejo is very inconsistent  ... so some colors give me no issues while others are a PITA .

Best advice I can give is just keep experimenting .

I really like the Paasche Talon  , it runs a .25 , .38 , .66 tips and the .66 runs a fan-air cap also , for large areas .
Maybe one day I'll buy a H&S to check it out  -- I think it may be better for very fine detail , but I have no experience with them and my Talon does everything I need it to do .

Model Air is consistent, Model Color isn't, simply because it takes more or less pigment to make the color as vibrant or as opaque as it needs to be. Not sure why the difference in consistency between the 2 lines, but it has always been that way.

I just keep a Qtip with thinner on it to keep the tip clear.

Thanks for the Talon suggestion, urumomo. 98% of the inconsistent paint delivery/tip drying problems I was having were due to the POS Harbor Freight airbrush I was trying to use.
Now, a related question to this topic: Vallejo airbrush flow improver vs Vallejo airbrush thinner.  Whats the difference? IS there any difference?

Loving life! Diving into a classic Renwal M65 Atomic Cannon I have had for over 40+ years.  I know there are a bunch of "collectors" who would scream "don't build it, that's a collectable" or "do you know how much that is worth???"
My thought: I didn't buy it as an investment. I bought it because I love the hobby!!!
I have had the diorama planned for it since I bought it in 1976!!!!

IDK about the flow improver over the thinner  -- I assume the flow improver is heavier on retarder
don't tell you much  :  http://www.acrylicosvallejo.com/en_US/model-paints/auxiliary-products/3

You building this thing ? :

The origianal Renwal model. Not the re-release by Revell.  I bought it when I was still in HighSchool and shoved it in storage with the plan to "get to it one of these days".  Typical Renwal kit, lacking on some details, mold marks, etc, but loads of fun, great challenge, lots of sanding and putty but coming together nicely. Photos to follow soon in the Armor section.

Thinner does just what it says, it thins the paint. It has some retarder and flow improver in it to help with tip dry, but for the most part it is there to thin the paint.

Even with Model Air, I thin it 1 part thinner to 5 parts paint. Cuts the surface tension of the paint, and just makes it flow better. Like putting a drop of soap in the water you use for the polishing pads to polish out a paint job.

Flow improver does one thing, improves the flow of the paint without thinning out the pigments/color, or at least that is what it is supposed to do.

I am in eastern Canada, just using the thinner is enough for me, but in dryer parts of the world, where the paint dries much faster, adding the flow improver would likely help a lot.
