So I've been using Krylon Flat Black Primer to prime my models and i notice i get a dusty result when sprayed on my models. This is not the problem however, as painting the models will usually get rid of it (though if you have ways to avoid this, please let me know.) My main problem is after my models are dry from priming and i'm handling them to paint, i notice that the paint kinda rubs off. The primer is no longer there and shows grey from where i've just touched it. I let my models sit for about 2 hours before painting them, but most of the the time, i wait a whole day to continue painting them. I also make sure to shake my can of paint for 2 minutes. Is there a reason why this happens? It never really did it before, so now i'm wondering why it does it now.

im pretty sure the dusting is because you're spraying too far away and the primer is drying in the air before it reaches the model
as for primer rubbing off of the model, that seems really strange. im assuming you've already looked closely enough to be sure the can says primer and not paint. i wont insult your intelligence.
i only use the games workshop primer cause it's convienent to get it while im at the hobby store. what's the price difference between the stuff you use and the $15 a can GW stuff?
edit: i googled around and it seems the krylon primer is about 1/3rd the price which i might consider if i had a LOT of priming to do(right now i do like 1 unit every few weeks so ill stick with convienence)
but i also stumbled upon some people having completely seperate problems with the krylon primer. chiefly inconsitency in it. sometimes people are having it be super watery and other times taking days to dry (link: http://www.reapermini.com/forum/inde...howtopic=31134 )

Yes.. the dusting comes from spraying too far away..
If you are spraying too closely, you will get rivulets of paint running down in areas..
As for the rubbing off.. this again comes from the spraying too far away.. If it is drying in the air, the bond to the plastic will not be sufficient.. (It already tried bonding while in the air)
How far away are you spraying from?
