I've had problems with the Vallejo primer but there's a couple factors that are most likely to be blamed (mostly user error):
- I thinned with water,
- I was a first time air-brusher.
I would like to try it again. I don't think it was oil or release agent - I had washed with dish detergent and water.
What's the best way to thin this primer for AB'ing? What pressure should I be using?
