Sd.Kfz. 7/1 (early) with Flak vierling 38

I recently purchased some of the MIG AMMO Dunkelgelb colours, ie. Mid War, DGI and DGIII. I like the colour of the DGIII as it closely resembles the color of the vehicle in the picture I posted previously. I sprayed the paint on but it took a long time to dry which I found unusual. The instruction on the bottle say let dry 24 hours but even after 24 hours it was still a bit tacky to the touch. This was my first time using these paints and I was not expecting that. The paint also dries with a satin finish not dead flat. This is not a problem ad weathering and filters will most likely take this away...I hope.
