Blown this isnt really the right place to ask shoulda started your own thread, but Ill answer anyway.
Fascolor needs to be sprayed through a .3mm tip if its unthinned and I use 35-50 psi when spraying it. YOu can thin an entire bottle according to parmas site by adding a teaspoon of water to it. You should apply parma's faskoat 2-3 layers after painting to prevent solvents like nitro from ruining the paint.
and this link will explain backing what colors with what types of paint.
