IL-2 STORMOVIK REVELL

Grzegorz Janikowski
Hi. Why, when I paint with Super Clear 3 varnish, I get such a white mist, a coating that I have to grind later. What am I doing wrong? What angle would I not use it appears to me.
Does anyone know how to handle this while painting?
Airbrush painted, not from can.
