Over the last few months I seem to be having a re-occuring problem with Humbrol matt Olive Drab 155.
Usually all Humbrol matt paints are bone dry within 10 mins or so, certainly within 30 mins max, yet the 155 no matter how much I shake the pots before opening, and stir the paint for minutes, before use, it still always takes 3 or 4 days to dry, seems to be very thick, and 50% of the time is drying as a satin!

Even if I try mixing in talcum powder to matt it down (which usually works) it can still dry satin!
Anyone heard of this before or any ideas what I can do about it.....I am wondering if Humbrol have had a bad batch or something?
I am not impressed by the paint going on well, and drying so badly that I have to almost wreck the kits trying to get it off again, or paint over again and again making the paint way too thick.
This has happend on different plastics as well as resin, so I am fairly sure it is nothing to do with surface contamination.
Also using different brushes and buying the same paint from different shops, one in Staffs, one in Notts!
