Grey Primer 200ml Bottle

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.

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.
