I primed a bunch of minis today (Star Wars Imperial Assault, plastic board game figs). After letting them dry, I noticed they were SLIGHTLY powdery. After doing some quick research, it seems as if this is a common problem and might have been because I was holding the can too far away. I'm going to pick up some Krylon Flat White Primer and try again this weekend.

Would it be okay for me to brush the minis off and just prime over, or should I completely strip them? If I should strip them, have people had success using Simple Green to strip Army Painter White Primer?

Thanks!

I prime almost exclusively in krylon, so in that regards you are good.

I have never sprayed directly over the powder 'clumps' like you are asking, but i have sprayed directly over other primers and it works fine. i imagine that the clumps would be exacerbated, perhaps you could try eroding them off with a new toothbrush prior to repriming?

Be careful of using paint thinner on plastic models, it can melt the details underneath, depending on the composition.

Was it humid out or did it just rain? We have that problem in Florida - our hot summer afternoons require you to prime and then come straight inside because the humidity is not good for your primer. Same goes with airbrushing as the paint can dry before it gets to the model. You may want to strip them and start over. I'd use Simple Green only because I don't have experience with the Star Wars plastic models. I'm not sure how durable it is. Usually, I recommend Purple Stuff (engine degreaser) because you can strip an entire army quickly in the matter of an hour or two.

There aren't actually only clumps of powder. I might actually paint one up as a test to see how it goes.

Nope, weather was pretty much perfect. 60 degrees F, primed in a garage, very low humidity in NJ.

Thanks for the advice!

Whatever texture is on your model before priming will be there after priming.

take a large soft brush of some kind, and srcub them a bit, this should knock off most of the grit.

(I use a stiff tooth brush for this).

If you prime over it, the bumps will still be there as others have said.

best of luck!
