I've had Army Painter's little portable wet palette for over a year now, and recently I've been working on my Guard army again, but it's revealing problems.
I thought the whole point of my wet palette was that it was meant to A: keep my paints moist between sessions and B: make thinning them easier, with thinning being as simple as just dragging the paint out from wherever I put the initial drop, barring paints that need to be very thin.
What instead happens is that the top surface of my paints dry out very quickly even when the sponge is kept saturated. This creates a dry coating of paint on top of which I can no longer thin paints, which effectively removes room on the sheet.
Any drops of paint I have on top dry out not completely but enough that they're no longer practical to work with.
I live in an extremely dry climate so I'm sure that doesn't help but the more I use it the more I wonder what exactly is the point? It really doesn't seem to be doing anything for me that I wouldn't accomplish with a dry palette. I'm not sure if it's just Army Painter's hydrosheets not being permeable enough or if I'm doing something wrong, but it's causing me a lot of frustration.
