Dullcote is being a knob! (help needed!)

[OrkyDave]

Hiya.

I am not a happy orkydave.

I have spent absolutley ages doing freehand on an Eldar fire prism, I was really happy with it so decided to give a coat of dullcote so I would not rub the design off finishing the tank. The F*&%$ng dullcote then spread purple from the dress (I can only assume) all over the freehand design ruining my hard work (and a customers commission). The purple was painted well over a week ago, so it wasn\'t even as if the paint was wet when sprayed.

Anyone know what caused this to happen, or what I can do to avoid it once I repaint the design? Its a lot worse IRL than the pictures.

Can\'t really see the leeching you\'ve described Dave, but Ho-hum... :/

Is the paint you used for the purple a regular acrylic? I\'m assuming you would\'ve mentioned if it was some different kind.

Can\'t think of any reason it would\'ve reacted unless you had maybe mixed some sort or extender or something with the purple...?

??? Sorry ???

 

[OrkyDave]

Nope, just regular Gw Liche and warlock, thinned with water only.

The leeching is evident on her collarbone, face, top of the head/hair and wings (although it kind of looks cool on the wings).

As I say, it is a lot more prominent in real life, but evident on the pictures still.

That\'s a bitch good job by the way....
best way to avoid anything like that on freehand I find is to first put a thin layer of watered down GW matt varnish on the freehand areas before dullcoting...The brush on Gw stuff aint too bad and your only aiming to lightly seal the paint before the dullcote does the real job...Also putting it on with a brush means if it does start to leach you can stop applying and limit the effect.....

It\'s one of those great mysteries and a great example of murphys law that it happens on your longest or favourite bit of work.....good luck with the next application....From the pics it don\'t look bad but I can guess in real life it\'s a bit of a bitch.......

I had a problem with dullcote turning scorched brown to purple once only. I put it down to spraying to much on and too closely. Wierd though its the same colour???

I had dullcoat melt a bunch of paint once. I promptly switched to GW matte varnish and it hasn\'t happened since.

My theory is that too heavy of an initial coat melts the paint. Often in the world of auto painting the first few coats you spray will be very light coats to acclimate the paint to the clear, then spray on heavy coats. This might be a technique to try.

To be honest the purple by the collar bone was just shading! I\'ve read on the boards that purple has a habit of running with varnish (usually brush on) so it may be a purple thing.

Thanks for the feedback guys, will have to seal it when its re-done.

I think too much to close and a combination of purple paint seems to be the culprit here.

Heres a picture if the skin before sealing- shows where the paint has bled a bit more

brush on or spray on?

spray - very light coat to build up.

If it were inks, that\'d explain things, too, as they generally take longer to dry than paints do (if ever, especially brands like Tamiya Clear Acrylics).

Bummer about the paint creeping osmotically...

Only thing I can think of is that the dye/pigment in Liche Purple must be really strong and that the initial spray of DullCote was too thick, allowing it to spread. I don\'t have Liche Purple, but I have the Vallejo equivalent and I know from personal experience that it takes twice as much color (if not more) mixed with it to tone it down compared to other paints... very strong purple color, I guess, and just didn\'t want to be limited to only the dress.

I guess on the positive side, now that the DullCote\'s down it won\'t spread any more, and any repainting using thinned skin colors will have a more realistic flesh tone due to the purple underneath? 8^)
