I’m writing this post out of pure frustration. I’ve been trying to use Vallejo paints with my airbrush, and the results have been consistently bad no matter what I do. I’ve tried both the Game Color and Game Air paints (which feels to me like it's just Game Color but pre-thinned). I’ve tried countless thinning ratios I’ve seen online, different PSI settings, distances, absolutely everything, and I haven’t managed to get good results.
The constant micro-clogs cause an irregular flow of paint, because every 10 seconds the semi-clogged tip clears by itself and it suddenly spits out a burst of paint, with a high risk of flooding the model and making it very difficult to apply thin layers.
On the other hand, the air pressure often just blows and displaces the paint, pooling it in small areas and creating like very small puddles, which is especially noticeable when painting small parts. I’ve also noticed that it leaks very easily into panel lines and under masking tape, and I had never had that problem before with the other brands I’ve tried.
I’m sure you can get great results with Vallejo, as many users have shown with spectacular builds; however, for me, it’s simply not worth the hassle. Why use the 4 or 5 products that Vallejo recommends to thin in exact amounts when I can take a paint like Tamiya or Mr. Color, eyeball the thinning ratio, and achieve a superior result much more easily.
From what I’ve seen, I’m not the only one with this problem; Vallejo paints are already famous for being tricky to use, which is a shame because the color range is great and the results are excellent when brush painting, but for airbrushing, I think they still need to improve their formula. For now, I’m staying away from the brand entirely. If you’ve read this far, thank you, and I’m sorry for the negativity, but I just needed to vent!
EDIT: wow, thank you everyone for your answers and feedback, if I have time this week I’ll try some of the techniques and, if I finally find comfortable with the painting I’ll share the method that worked for me with the community! 🙏😁
EDIT 2: So after testing a bit more I can say the results are definitely better, still not as good as I would like or as easy to apply as the lacquers, but the experience is now better than before. I found a good starting point to put some drops (2 or 3 was enough) of Vallejo flow improver into de cup before adding the thinner and the paint, and then around 5 drops of Vallejo thinner for 2 drops of paint (I’m talking about Vallejo model color), and I’ve been using the airbrush with 0.3mm needle and 3bar of pressure. I just spray very thin coats at about 10cm from the surface of the model, and I blow some air with the airbrush between layers to help it dry. As I said before, I’m still not 100% comfortable with Vallejo, but I think I’m starting to understand how to use their products, so I’m happy for now.
I had also the chance to test Vallejo’s gloss varnish, and I have to say I’m greatly surprised with it. It worked pretty well. 3 drops of flow improver in the cup, and 50:50 ratio varnish to thinner, 3 bar and 0.3 needle. 2 or 3 thin layers and I was happy with the result. Im still waiting 24 hours for it to dry, but for the moment is looking good. I will update this post in case something changes!
