Hello. I noticed that Humbrol Acrylics have recently changed bottles. I was pleasantly surprised when (maybe 10 years ago?) Humbrol launched their acrylic range in the flip top pots. They brushed and sprayed great when thinner with either water or Tamiya acrylic thinner - I got really good finishes. The paint while thick, thinned and covered well. Then Humbrol started producing the acrylic in screw top bottles while producing their own proprietary thinner. At first all was well but then the quality (in my opinion) nose dived. Coverage with either hairy stick or air brush became horrible with beading the norm. I tried washing the plastic, priming, and using Humbrol‘s acrylic thinner, but also other types to include adding a bit of dish washing soap. No luck - just horrible beaded finishes. Okay so long story short, do the new bottles indicate a change in quality or formula? Has anyone tried them and what are your experiences if you did? I guess it is really frustrating when one watches the tutorial videos from Humbrol and can‘t replicate the results anymore. I am relatively skilled with using Humbrol enamels, Tamiya, Gunze, etc. so it really puzzles me why Humbrol Acrylics are so trying - especially after I had good experiences with the when they first lauched. Thanks for any replies or advice!
