My test of the Two Thin Coats range is going slowly, mainly through being distracted by other things. I found two recent video reviews on YouTube which do a good job.
Broadly speaking the findings are the same as my initial impressions and first painting experience – the metallics in particular a great, the colours are good but the small range means there are significant gaps.
Here is a video from Ninjon:
Ninjon notes that many of the colours map directly to colours in the current citadel range and are clearly intended as an easy replacement.
Stahly notes that price-wise this is not a range from the bargain conscious, but that the paints have properties that can make them attractive.
I will chime in with my own thoughts once I have finished testing them out – turns out paining all your miniatures makes reviews like this more tricky!
