Hi again Antoni
I must admit I'm pretty useless when it comes to thinners - I seldom use manufacturers' own brands and I just experiment with with the usual culprits. For Agama paints I've found Isopropyl Alchohol works well, or good old Windolene as a substitute for water (the detergent helps the paint flow better).
I found your Karaś notes - cheers, they're a huge help and your model is looking great! I've moved the thread to the WW2 forum. Of course, it reminds me that's another stalled build in my pile - I really must get on with my own Karaś this year! 2007 is starting to look busy already!

:-)
All the best
Rowan
