Have you used Etac? or is there some reason thats not a good option?
Only reason I've shied away from it is because when i first looked at them their additive system uses wierd names and the descriptions of what each does overlap and read in a very confusing manner.
Yeah it doesnt seem like they push com-art much. My thing with it is that it seems kind of watercolor-ish to me...but it may be in my head because I know that was my first impression when looking at the little color squares printed on the package i bought....which seemed faded. It also seems to bead up at odd times like maybe its very sensitive to fingerprints on less porous surfaces or something.
The Com-Art colours are far more vibrant than what's printed on the packaging, the packaging seems badly printed.
I've tried e'tac but didn't like it at all, it rolled up when I tried to erase it, some might say that's down to a bad bottle but I had it with several colours, I remember Mitch thing it and Geraldo found it a bit sticky.
I plan to stick to the paints and other materials that gave me the most joy, it was messing around with e'tac and trying other stuff that caused me to give up several times, so if I want to keep airbrushing I've got go with what I know works for me, not just paint but brush and substrates too, other than Com-Art if I can find it I have no intention of risking throwing in the towel again by moving to yet another paint.
I can't use anything createx because even just what hangs in the air after I take off my mask would kill me, I have always worked in my house, might be different if I had a work place outside of the house, but no chance of that ever happening.
