sp4rky Posted July 20, 2011 Share Posted July 20, 2011 Hi guys, I'm a bit disappointed with my GW Black Undercoat spray. I was expecting it to last quite some time (as it costs a tenner and is quite big) but after undercoating around 30 Space Marines it's run out. At least I assume it's run out because all I'm getting is clear spray. I'm quite surprised because my last can lasted me around 4 years on-and-off usage and I guess in that time I would have undercoated more than 30 guys (I know of at least a Land Raider and 3 Rhinos that I did with it). Does this sound like premature running-out of paint in my can or is this perfectly normal? Answers on a post card please ;).

barry_hhh Posted July 21, 2011 Share Posted July 21, 2011 this does seem like it has run out quickly , however , if you have sprayed the 30 marines separately there will have been more over-spray hence more wasteage . even then it seems as if it may have run out early.

Elric the Silvercoat Posted July 21, 2011 Share Posted July 21, 2011 That was an early run out because I undercoated 100 marines with one of my can one time so yea.....then again I can't remember if it was GW or another brand.

Leonaides Posted July 21, 2011 Share Posted July 21, 2011 Did you shake it properly? What temperature was it while you were spraying? Did you do short bursts of long continuous sprays? How closely did you space the marines? Was it a tuesday? All of the above (well, apart from tuesdays) can have an effect on how much propellant or paint is used. For example - I have a750ml can of line-marking paint that is still about 2/3rds full of paint but has no propellant left because someone didnt shake the darn thing up enough before using it...

JayeL Posted July 22, 2011 Share Posted July 22, 2011 Funny thing there is a guy on warseer asking the same question (although his was with regards to the amount of dark eldar undercoated). Maybe there is a bad batch of Chaos Black with low volume in the tins out there.

DV8 Posted July 22, 2011 Share Posted July 22, 2011 Don't forget that GW Black "Undercoat" is literally just black paint in a can, and not actual primer. Hence it's actual effectiveness is worse than that of actual primer (and you'll be using more to achieve the same result). Of your previous can lasted 4 years (so I'm assuming that you bought said can a little over/under 4 years ago), you would have been using actual black primer. I recommend switching to an actual primer (I recommend Krylon Black Primer) as it'll be cheaper and more effective/efficient.

Ekgar_Wolf Posted July 29, 2011 Share Posted July 29, 2011 My last can run out after undercoating 60 Orks. Now I use Vallejo Polyurethane Primer (200 ml) with airbrush, and it is far better and cheaper than any other spray option (dunno about Krylon as it is difficult to find in Europe).

esinhorn Posted July 30, 2011 Share Posted July 30, 2011 I miss the old school true GW primers they worked great. Now I use Armory Black Primer and Grey Tamiya Fine Surface Primer Link to comment https://bolterandchainsword.com/topic/234616-how-long-should-a-can-of-gw-black-undercoat-spray-last/#findComment-2833757 Share on other sites More sharing options...
the_cheat137 Posted August 5, 2011 Share Posted August 5, 2011 The price difference is pretty big; you can get about four cans of Krylon primer for the price of one GW can.

DV8 Hmm... if they switched, that would explain why I keep hearing some people say that the GW sprays are just paint, and some say that they are actual primer. Good to know, I was really confused on that point before.

Gamelli Streamfisher Posted August 7, 2011 Share Posted August 7, 2011 I heard a claim from a GW employee that their "primer" (the new stuff) shrinks as it drys in the model whereas other brands of spray paint expand to fill gaps. For painting a highly detailed miniature, I wouldn't want the detail getting filled it. Is this a legitimate claim?

Err, if this were the case, then they aren't using a primer (it isnt in the first place) but more likely a vinyl dye...which actually sinks into the plastic, rather than providing a good colour and surface to paint onto... -kizzap Link to comment https://bolterandchainsword.com/topic/234616-how-long-should-a-can-of-gw-black-undercoat-spray-last/#findComment-2841256 Share on other sites More sharing options...

heretic??ME?? Posted August 8, 2011 Share Posted August 8, 2011 GW staff are sales man now simple as. I asked red shirt the other day if the purity seal varnish was matt or gloss? His answer: It's somewhere in the middle!! Pick up key colours but grab essentials from other suppliers. Test their stuff out as well before hitting batch's of models.

His answer: It's somewhere in the middle!! To the best of my knowledge, that's actually true... Yup, it's supposed to give a satin finish. But I would recommend to stay away from GW varnish either way.

simon-042 Posted August 9, 2011 Share Posted August 9, 2011 I did use the Citadel black spray for a while but recently switched to Hycote Grey Primer having seen it mentioned on this site as a good replacement and a "true" primer. It's designed to be used on car bumpers, but is acrylic based and matt leaving a grey colour between fortress and codex grey when dry. It feels slightly textured once set but hides none of the detail providing you shake up the can well and maintain a good distance between the nozzle and the mini. Clearing the nozzle after spraying is a good idea too! And its much cheaper...

Alleton Posted August 13, 2011 Share Posted August 13, 2011 I've used dollar store black and white spray paint with satisfactory results, I can get roughly 7-8 cans for what one can of GW paint/undercoat costs.
