Reviews : Vallejo Grey Primer 200ml Bottle

This primer is a acrylic primer. That's what the polyurethane means. This means that it's not very durable as it's grip on the plastic is weaker. Acrylic paint will not damage the primer and neither will enamel paints. Lacquers are a bit trickier as too much will melt the primer (and possibly the plastic underneath) and cause the paint to become splotchy. However, if you bump a key or something hard onto the bare primer, it will scratch. It is not very durable at all. This issue is reduced when paint is applied as the top coats will harden and help protect the kit. If you try to sand this primer, then you'll probably fail. Because it gets damaged so easily, the sandpaper will only do that more. The grey primer covers much better than the white primer and is actually smoother. This means that it sprays smoother and is probably thinner, too. Unfortunately, beyond that it's just like the white primer in quality. Which isn't that great... Just go with a Tamiya spray can primer.

I used this for the first time today. Up until now I always used Tamiya but the local places ran out and also a lot of online places were out of stock for a while as well. I use Vallejo paints on my models and I figured I would give this a shot as well. I was happy with how it worked. I did not have to thin it at all for it to work in my airbrush, which is nice for me as I am still learning a lot about airbrushing as I go. The only thing I would have to say negative and really this probably falls more on myself is that the color seems to be very white.

I was recommended this primer for cold months as I have limited access to space that I can safely spray indoors. Tried it as a brush-on primer, and it works just fine. The coverage is good and it's pretty forgiving as a brush on, but I did have a couple areas where I needed to wick away excess. As a brush-on, it did tend to pool more in deeper details and was a bit more labor intensive that I would've liked, but was perfectly functional for what it was - a makeshift solution for those of us without airbrushes in colder weather.

Had to find a new primer that I could use through my airbrush as it was too harsh of a winter here where I am located to even consider a rattle can. This was just the ticket... was almost ready to spray, great coverage, and very easy cleanup afterwards. Only downfall is that the Grey was a little lighter than what I expected and had trouble seeing the first coat go on. Easy solution... add a drop or 2 of flat black paint to help darken it up a little.

Follow the Vallejo directions. It's worth watching the primer video on the Vallejo site. I've been using it at 15 to 18 psi in a Grex airbrush. Remember that it is a polyurethane, and does not achieve full cure for about 24 hours at 68 to 70°F at relative humidity of 50%. Contrary to what another reviewer said, when properly applied and cured it can be wet sanded. Sufficient cure time is critical if you are going to sand it.

Be very careful when using this primer. DO NOT ATTEMPT TO SAND THIS PRIMER. It will chip and peel when sanded. I have found this out the hard way. It goes on very nice and smooth. This paint would be great for small detail parts where acrylic top paint are being used, not for priming model car bodies where sanding is involved. No where on the bottle does it say do not sand.

You can't go wrong with this primer when working with an airbrush. Straight from the bottle it flowed beautifully through my Badger airbrush. The primer self levels and leaves a great surface for follow-on painting. I would recommend that you allow a full day for the primer to cure. I can assure you it beats the pants off Model Master primer!

Sprays OK, but I have to say it doesn't sand well. Works well on military models, but If you are doing a model that needs a smooth, glossy surface like a car I would look elsewhere. Doesn't take to wet sanding before color coat. That was disappointing.

vallejo primers are excellent they provide smooth even coverage and are self leveling. they can aslo be airbrushed straight from the bottle without thinning . i would highly recommend this product .easy and very forgiving even for the beginner

You can put this straight through an airbrush, but you can also brush paint it if you need to. I haven't had to thin it to spray through an airbrush which is nice!

This.is the best primer I have ever used it goes on in. light this primer. Will be the only primer I will will ever use again

Excellent product Highly recommended...very smooth for air brush and dry brush.you don't have to use thinner.highly recommended

This primer is excellent. Has great coverage and flows nicely out of my airbrush without any problems.

Excellent Primer for use in an airbrush. Sprays on very lite and does not cover up detail.

Love this primer makes paint work so much easier. Primer really comes in handy.

Vallejo primer goes on very well with an airbrush and gives a great finish.
