In regards to the enamels, I wouldn't risk it. There's plenty of acrylic options to choose from
And speaking of people repainting their Hulkbusters in the standard colors, I more or less just finished mine. The nearly complete lack of paint just just killing what would have otherwise been a great BAF. There might be a few things to touch up, but I definitely feel like it's a vast improvement, especially with so many of the details just completely unpainted.
So, now I just have to decide if I want a glossy seal or just standard matte...
