Vallejo - Surface Primer Color | Grey Acrylic Primer 60 ml (2.02 fl.oz.) | Matte Finish and Fast Drying | Perfect for Airbrushing and Great Adhesion to Figurines and Scale Models

I tried airbrushing this product on GW plastic models and some BattleTech models from CGL.The product sprayed out nicely once I got the airbrush dialed in. I used a single action external mix siphon feed airbrush at about 25-30 psi. I probably could’ve gone lower pressure, depending on the mix (as mentioned below).I experimented a bit with adding in some thinner to the mix at about a 1:2 thinner to paint ratio. It didn’t seem to need the thinner to work though, and I was able to get a good stream by using the straight product too.I take this as a good thing, as it doesn’t need thinner but it plays well with that if you want or need to thin it. It might be nice if you want to do a very thin coat.Adhesion was not a problem, though by test spraying it I could see that it was kind of runny if there was just too much paint in the mix. That was fixed by adjusting the airbrush.The grey is quite like the Corax White spray from GW. It really looks quite white unless you have a pure white against it. This isn’t a drawback, but it does seem to make this more suited for lighter color schemes than darker ones.Overall, I would recommend this to anyone with an airbrush and a lot of models to prime. While $20 for 200ml isn’t super cheap, the amount of priming (and quality priming at that) this bottle can do really blows away the canned competition. You need to have the right gear and sufficient project to justify this, but I don’t think it is a purchase anyone will regret.

Primer works perfect, applies even and does the job

My husband is a total Vallejo fan boy. His hobby is 3D printing and then painting various models. He loves Vallejo paints and primers. The primer works straight out of the bottle in his airbrush. Vallejo is all he uses and has for years.

Vallejo airbrush primers are just generally 'pretty good.' I typically use the black an don't have any real issues with it. If priming several models at once or larger pieces - essentially any longer airbrushing sessions - you will run into tip dry and the paint in your cup with start to thicken. Keeping an eye on your needle and the paint still in your airbrush cup will go a long way to alleviating your priming frustrations. The grey looks good and goes on smoothly, just like the black. It does have a tendency to thicken up and 'gum up' the airbrush a bit more than the black. Basically, where with the black you can add a drop or two of thinner and just go... you'll really want to watch the grey a bit more and play with the thinning to make sure you're still getting coverage along with a smooth spray. Anyway, if you airbrush regularly you'll figure it out. Where this shines is the VALUE. You'll be able to prime HUNDREDS of minis with one bottle. That is no exaggeration. $12-$16 dollars usually is what this goes for. Compare that with a single rattle can from Citadel or Army Painter. It's absolutely no contest is you're trying to save some money. I have not had any issues after years with Vallejo airbrush primers with adhesion. BUT - I will say - and I think this is a bonus - it strips very well. Soaking in Simple Green will strip paint and primer with a couple days and an old tooth brush. I personally like that. And since I don't have adhesion issues - this is a no brainer. It allows me to relax and if I make mistakes I don't sweat it. Another bonus of airbrush primers is you won't run into any issues where a can isn't mixed and gives you that hydrophobic coat. You get a smooth prime every time. Again, providing you know how to airbrush. Anyway, enough rambling. This is great. Saves money.

great quality easy to apply

This is a great primer.What the bottle doesn’t say is that it’s made for airbrushing, until you read the directions for use.I don’t have an airbrush, so I applied this by hand. It is a primer and not a base coat. What I mean by that is that when you’ve finished applying one or two coats, this will stay a little sticky until you paint over it. You do not want to leave this exposed for a gray paint color, you absolutely need to paint over it.It does a very good job covering, and I haven’t had to put more than two coats on anything yet.It helps the paint hold on to the surface.This will be my go-to primer from now on.I also found that it covers easily and I needed to use less of it than I expected, so this bottle will likely last me quite a while.

Si dudas algunas es excelente este producto me encanta la textura que le deja a mis piezas y funciona a la perfección con cualquier aerógrafo sin necesidad de tinner

Works well with a large tip nozzle straight out of bottle. PSI set at 40 and do light strokes. Used colored acrylics following and model looks great.
