Okay I've read every post/topic on airbrush problems but still can't solve this one.
Trying to airbrush Tamiya X-2 white but it always forms an orange peel effect and is never smooth. I''ve tried adding more thinner and this just makes me add more coats but with the same result (it just takes longer!!). My psi is around 20 ,should it be less? And I was spraying about 5-6 inches from the model although when I came in closer it just built up real quick.
Any help would be great thanks.
