Testors has NOT been pushed out of the market. It is still in business as a brand, and continues to develop and sell new paints. The only change is that it has dropped military colors in its MM line and developed new colors for a broader range of market. They have developed a new line of lacquers (I suspect they are acrlyic lacquers) that I like very well. They are quite similar to Tamiya acrylic lacquer.Their color-shifting paints are new, appearing after the so-called death.
They have expanded their line of metallic enamels such as gold, silver, aluminum, etc. Their latest flat aluminum is very nice, as is their Chrome. The latter is great for touchup on foil flaws and gaps.
The obituary for Testors was highly exaggerated. My local HL manager says the Testors paints sell very well. I have no connection with Testors, just a long customer relationship- I used Testors paints on my first models over seventy five years ago, as well as their model airplane glue. They are still my goto paints for everything except polished or lightly weathered aluminum, for which I am an Alclad fan.
I see more paint brands on the market now than ever before in my seventy five years of model building.
