Airbrush Woodland Scenics liquid pigment

[WPA]

I have only colored a few tunnel portals with the WS concrete color so thanks for heads up on using sparingly.  I will eventually have a bunch of castings to color. I was thinking of using the black to airbrush some coal weathering on a Cornerstone mine kit.

I’ve used the WS pigments on all of my Plaster of Paris and Hydrocal rock castings and they are really absorbed quickly especially the black.  I have to use it very sparingly or the rock castings are toast.

 

I’ve never attempted to spray it, I would expect that to be way too dark.

 

These rocks have a very light amount of black, the Umber and burnt umber have multiple coats.  Black really does a number on plaster castings.

Anyone airbrush using Woodland Scenics liquid pigment?  I have black liquid pigment and a coal mine to detail and wondering if someone used it, what did you thin it to. Newbee to airbrushing. I searched the forum before posting but did not see anything, but the search also did not seem to work with any related term. Thanks
