I recently did a model and used chalk pastels for weathering. I did really nice job (I thought) only to have all the coloring disappear when I over sprayed with a clear, flat coat. When the pastels got wet, they just vanished…at least most of it did.
Is there any special way to do this?
Thanks,
Mike
Everything i have read says they must be added after the flat coat, there’s no other way. They are quite resilient as long as its not handled to much.
I concur with Bish. Any clear coating you put over pastels will greatly reduce the effects of them.
I have had the same problem, and have never found a solution. Some have told me that they use a fixer, and apparently some brands of weathering powder make their own special fixer. I have experimented with mineral spirits as a fixer, and it might have helped*.* The mineral spirits allow the powder, or chalk, to flow into recesses, and when it evaporates you get a “dusty” line.
But I have to say that nothing I have tried really works well. The commercial weathering powders I bought hold up slightly better than when I used chalk, but would still disappear. I now do as Bish suggested, and leave the weathering powders without trying to clear coat them.
I had exactly what you described happen to me, had a kit that I thought looked good, put a dull coat over it, and there was not a trace of pigment left!
I’ve used this method to weather model rail cars, and had to do it in layers.
As mentioned earlier start with a clear coat (I use dull), then apply the chalk. Seal with dull coat and repeat as required building up the effect.
Thanks guys, I was afraid of that. I’ll try the multi-layer dull coat apps and see how that goes. Either that, or try to get better at weathering with spray or dry-brush.

Mike, is it armour, aircraft or something else your building.
i agree with bish. i wear a cotton gloves to handle the model after painting and don’t spray anything over the powders. been using tamiya but will be trying railroad FR something, pastels and eye shadow.
