So I had my first go at using an airbrush and painting latex today after watching Tim Martin's tutorial and hit a few snags.
1) No matter what ratio of rubber cement/thinner/oil paint I used, it was always way too watery and felt like I was simply spraying water as opposed to a mist of color. Is this a ratio issue, or an airbrush/compressor setting problem?
2) When I finished, I was quite pleased with the results (even if it was a struggle), but a few hours later, I found that the paint had dried with a very dull look; like the colors became desaturated or the piece became coated in dust (it hadn't). When the latex was pulled or twisted, the paint "broke" a part, and became duller and even let some of the latex show through.
3) Also, are there any ways to seal the completed latex piece (while keeping flexibility)?
4) For the completed project, I'd like to have some of the skin appear slightly wet (again, while keeping flexibility). Will Tim's epoxy trick work for this, or does the epoxy crack?
5) Tim says to always use oil paint, while other videos the artist used acrylic. Is there a reason why someone who would use one over the other?
Any ideas of what I'm doing wrong? I can paint by hand pretty well, but the airbrush is still a mystery to me.
