Hi combat,
some time ago I had the same problem, probably is the thinner, I solve the problem with a mask with air filter, open window (also in winter) and airbrush session no more an hour.
I like the Vallejo paints , I use them for to paint the details on the kit and for the figures. I'm going to built a little base for the Kubel and I think to add one or two figures from Alpine Miniatures. I will put the photos in progress.
This kit it's very easy to build and with an pe set becomes very interesting. I found a bit of photos, if you think are useful I send through wetransfer.
Have a nice weekend.
Mike
