    Gesso Experiment.

    Okay so as everyone knows I am new to the forums. I have been building gunpla for over 15 years and I really wanted to take my kits to the next level. I have been a miniature painter for a long time so I thought why not paint gunpla? So instead of brushes it seems like everyone uses an airbrush. So I bought myself an airbrush and I have been loving it. A few weeks ago I decided to start experimenting and going outside of my comfort zone.

    So first I started experimenting with Liquitex Basics and airbrush medium. I add a bit of retarder and some flow aid and man do I love the finish I get. A nice matte finish for a guy who isn't the biggest fan of shiny fresh off the assembly line giant robots.

    That got me thinking. I have primers that are 1000, 1500, and 2000 grit which of course change the finish of your paint and topcoat. So here I am thinking I would really like to see that military-esque finish that looks like it has almost been sand blasted. You know that thick paint that you know isn't going to chip for a good long while, but when it rusts you can see all of those little specks. This is where liquitex gesso comes in to play. Basically it is just acrylic gelled with some fine sodium bicarbonate floating around in there. It is used for priming canvas. Since it is liquitex acrylic it is compatible with their airbrush medium. So in my little lab I mixed up a batch of the white gesso, a few drops of Mars black, some paint retarder, some flow improver, a little bit of alcohol, and I topped it off with some of the airbrush medium. I mixed it up and it looked great. I pop a little bit in my airbrush and low and behold it sprays flawlessly. I put it down on the back of a clear plastic spoon and it primes very well. I let it dry and it had just a little bit of sparkle]to it. Then I took some of my already mixed red airbrush paint and sprayed it on top. I loved how it looked it was exactly what I was going for. I put a little matte topcoat over it after it dried just to take away any of the shine that I didn't want and I was left with the following experiment. Tell me what you think about this guy's. I am super happy about this and I am definitely going to be using it in the future for a build.

    Tl;Dr I took some liquitex basics gesso and mixed it till it was like milk. Fired it through my airbrush and got this result that I am stoked about.

    LOL that thick globby looking paint that military vehicles have is mainly because they were Painted by hand with big thick crappy brushes, by impatient privates and Lance Corporals.

    I think the rough look you are talking about is actually due to the parts of the tank under the paint being cast metal. Like this https://depositphotos.com/81462122/s...tank-kv-1.html . I think the effect you got would look great on some Zeon mobile suits.
    If it ain't broke.... you ain't tryin' hard enuff.

    That is the look I was talking about! I would love to do some Zeon suits in this sort of method. Thanks so much for the input man.

    I wonder, try this on a spoon first. What if you took some putty thinned it out and put a nice smooth but very thin coating over something then when it was just about dry. Brushed it with a toothbrush and "chipped" it then painted it. I wonder if that would give you the uneven and pitted but with no sharp edges, that you are looking for. That would give the paint different levels and an uneven surface. Poured steel has those little pits and uneven spots but is still "smooth" to the touch, so no hard edges. Just a thought. I might try it as well.

    I will definitely take a look into this as well. Seems like it could be a good idea.
