Hi there... New to this board but I have used Fusion paint, allot!
I have painted models, replica movie props and Star Wars armor for costumes with it. The only problem I have had is using the white, but I was putting it on a X-Wing helmet. This problem was more the item I was using it on than the paint.
Here is a picture of one of the models I have used fusion on:
This is a Star Wars TIE Fighter Pilot helmet I have done using Fusion black, the grey and green are not Fusion and I have had no issues using other paint on top of it:
