When doing very small parts or fine lines. Useing a smaller needle does it mean you need to thin more or less?
This is with acrylic paint.

Smaller spray tips require a less viscous mixture regardless of the coating being sprayed .
Most acrylics that are spraying fine with a large or medium tip will spray fine in the smallest tips - like .2 or .25 mm .
But , it's just something you need to experiment with .
Overthinning will create a weaker paint film or even runs .
