cheers epic,

Next time i clear coat em I'm digging out the air brush and using brush-on thinned down

For those of you who want to know i just used red ink washed over the figs with a little matt varnish mixed in.

It's atmospheric conditions + Purity Seal. If the air's wrong (humidity + temperature), it'll do that.

Best fix I found was to wait til the weather's a bit warmer and give the models another coat. If I remember right it's the solvent in the spray dissolving the clouded layer enough to make it go clear again.
