Panzerjäger - Major SNAFU

The idea was to paint the entire model in "German grey", then use the "hairspray technique" with AK's chipping fluid (as I did earlier with the M48's scissor bridge), go over with the sand-coloured base and green/brown camouflage, then start (gently) chipping away.

  1. The chipping fluid was spraying iffy today. It sprayed on very weird, widely known as "orange peel"-effect.
  2. Free-hand airbrushing, even with the finest nozzle my Aztec has, still gives an insane amount of overspray.
Let's address this last one first. I used the paint unthinned and dialled the pressure to the absolute minimum of around 7-8 psi. With the finest nozzle, I brought the airbrush in really close (about 1-2 cm). I could draw a relatively fine line on a piece of paper, but on the actual model it was rather difficult to 1) keep the paint flowing and 2) draw a line or curve at the same time. 
On the model, there is overspray AND the paint tends to run away. I can only guess that on paper it's easier, because paper absorbs some of the moisture, whereas a hard surface will produce spatters (albeit very small ones). This close up, the pressure seems still too high, as the paint runs away in tiny little spiders, but I can't get it lower than this. The only thing to do is move the airbrush further away, but can you guess what that does for the overspray? Correct!

Anyway, below is the result of my first free-hand camouflage airbrushing session. I'm not sure which parameter to play with to make it better. The green is okay-ish, but the darker the colour, the more obvious the overspray becomes.

On to issue number two. Compared to last time, the chipping fluid wouldn't spray very well, resulting in it going on the model way too heavily. I used 4 different nozzles, but couldn't find an acceptable way of spraying it. I'm guessing I'll need to do something to the fluid itself, i.e. thinning it.
I only realized how heavy the "hairspray" layer was until I started chipping. As soon as the surface became too wet, the paint started to wrinkle. When poked with a brush, the entire layer of paint came off like a snake shedding it's skin.

That's not chipping, but STRIPPING!

On the basket, it's easy enough to remove all the paint and start over, but on the turret I did not fancy doing that, with all those tiny pieces attached. So, I bit the bullet and very carefully chipped away some of the paint. Less is more, when it comes to the amount of water you're using.

The result is .... meh, good if you want to show how this chipping stuff works, but also illustrates it's easy to go overboard with it. I don't want to redo the turret, so this is how it'll be.

I had already sprayed the entire kit with the chipping fluid, but only painted the turret and basket. Seeing the results, I think I'll just give the entire kit a nice bath to remove the chipping fluid and start over, but more carefully.

  1. It is always hard to get thin lines, I also think when we test and things work the pressure on the real items tends to stress us as well. Shame you have to send it to the bath.
