Ever since Hornby brought the production of Humbrol paints back to the UK, all my examples in the newer branding (seen far left) have been rather quite poor, too thick, too thin, too greasy, non drying! Streaked finish. Whereas the older ones (second from the left) are absolutely brilliant paints, never had a single fault with them, that goes for the other 2 on the right hand side as well.
Now I don't know if this is accurate but I was told ever since they brought the production back to the UK they have changed the formula of their paints, could this be the reason why they are rubbish? Btw does anyone know of the history of the tin second form the right? It seems to be a rather short lived livery as I've only got 2 examples....
Please bear in mind this is what I've personally experienced with Humbrol paints, your view could be completely different but this is what I've experienced, after wasting too much on the newer tins I've decided to try tamiya paints, so far so good!
