orcsoul Posted August 23, 2007 Share Posted August 23, 2007 So today I thought i'd be lazy and try my hand at spray priming some of my as of yet untouched 'test' mini's... of which all are plastics from GW... went out and got me a can of black duplicolor sandable, set my little station up, shook the can up real well for a while, and started sprayin from about 8-10in away in light coats. After maybe 4 light dustings of primer per side of the figure (questionable moment one) the figures were by and large evenly primed with only the difficult to get to undersides left with patches of unprimed surface. Deeming that acceptable, I departed for a number of hours to let the primer dry and set on the figures.. I get back after letting them dry indoors under constant air flow for a good 6 hours or so, and find that the primer hardly managed to adhere to the plastic. It's hardly more than a thick black coat of dust on the figures that rubs off almost in its entirety when touched. (questionable moment two) Is it something i did wrong? Something wrong with this specific can of primer? Something about plastic that duplicolor primer doesn't like? Quote Link to comment Share on other sites More sharing options...

They may have had mold release still on them which could have caused your primer problem. Quote Link to comment Share on other sites More sharing options...
orcsoul Posted August 23, 2007 Author Share Posted August 23, 2007 Actually yes I did.. used dawn soap and a soft tooth brush and scrubbed them all down... could it be that I didn't scrub quite hard enough? Quote Link to comment Share on other sites More sharing options...
Cerridwyn1st Posted August 23, 2007 Share Posted August 23, 2007 What were the weather conditions like when you were priming? The affect you mention happens most often when the paint dries in the air before it hits the mini, causing a dust-like coating instead of the nice, even coverage. Maybe you were farther away from the minis when you sprayed than you thought. That would also cause the problem you describe. Try this. Get an old pop bottle and glue a mini to the cap. Spray in light coats just a bit closer than you did yesterday, turning the mini so it is evenly coated. Let that dry and see what it looks like afterwards.

orcsoul Posted August 23, 2007 Author Share Posted August 23, 2007 Hmm I didn't think about the paint drying before hitting the mini, Thanks! ... I'll definately give that a second thought and spray a bit closer next time I feel like having spray primer blown back in my face by a sudden breeze.. lol... washing that stuff out of your hair and nose is quite fun.

You don't get your face on top of it! How close do you hold the things when you prime? Inhaling that much primer can't be good for you. BTW, I've used dulicolor sandable in Florida's humidity and it still behaves pretty well. The only time I've had the problem you describe was with Armory primer. Could brush it off with a toothbrush. I think in my case it was a combination of a bad can of primer, not enough shaking of the can before spraying, and holding it too far away.

orcsoul Posted August 23, 2007 Author Share Posted August 23, 2007 Oh I was holding the can itself pretty close to my body yea, 3-4 inches from me maybe.. then the wind blew in a bad direction and it turned into a momentary self priming job. But the figure itself i hafta guesstimate was closer to a foot from my body. I just happened to be in the wrong place at the wrong time when that freak breeze kicked in yesterday.

Madog Barfog Posted August 23, 2007 Share Posted August 23, 2007 Uh, I hold the can with my hand, an arm's length away from my face. It's much closer to the mini than me. Weather has a lot to do with priming. The weather in the US has not been very favorable lately. Quote Link to comment Share on other sites More sharing options...
orcsoul Posted August 23, 2007 Author Share Posted August 23, 2007 Yea yea yea.. some people glue their fingers together.. I spray prime my face :P Quote Link to comment Share on other sites More sharing options...
vutpakdi Posted August 23, 2007 Share Posted August 23, 2007 I've used Duplicolor on old plastic Battletech minis at up to 65% humidity, and the Duplicolor worked just fine. I normally use Duplicolor if I'm spray priming, and I haven't had any drying or rub off problems. Ron Quote Link to comment Share on other sites More sharing options...
SaintRigger Posted August 23, 2007 Share Posted August 23, 2007 I think the duplicolor is meant for metal - so this may be the problem. If you have a metal model, give it a try. The new GW black is meant for plastics, and works brilliantly on plastic, but is miserable on metal. Quote Link to comment Share on other sites More sharing options...
Cerridwyn1st Posted August 23, 2007 Share Posted August 23, 2007 By the way, Orcsoul, if you catch me at War Dogs I can show you priming technique. If we ask nice Devon should let us go out back to prime. Quote Link to comment Share on other sites More sharing options...
PurityThruFire Posted August 24, 2007 Share Posted August 24, 2007 Primer in the face is better than the blast of spray paint stripper I got in my eyes. Ever had your eyes swabber out in an ER, not fun, not fun at all. Sounds to me like a case of spraying to far away from the mini and yes, Duplicolor is meant for metal autobody priming, though it is my favorite black primer for metal minis (favorite white is and will always be Tamiya). Krylon black primer works well on plastics. Quote Link to comment Share on other sites More sharing options...
orcsoul Posted August 24, 2007 Author Share Posted August 24, 2007 Okies.. if Duplicolor is good for metal/pewters.. got any suggestions for Plastics? Krylon is good for them? Looking for quality with spray primers that are good on plastics... and if Krylon is the way to go, which specific Krylon is it? They make like a dozen different Krylon primer variants. Or would you guys suggest the GW Primer for plastics? Though I've yet to see that, I imagine for the size of the bottle you're paying way too much when compared with Krylon or another brand.

PurityThruFire Posted August 24, 2007 Share Posted August 24, 2007 The Krylon primer I used to use was in a white can with a couple of circles on the front in varying shades of grey. Much, much, much better deal than GW, just be careful about spraying too much. Try to keep the can about 8" away from the mini and do a couple of light coats.
