I haven't painted STTNG grill, but I did paint my Time Fantasy grill when I was restoring it. (It isn't originally painted but I custom painted it) I used the same paints (water based latex acrylics semi gloss custom mixed to match original colors on cab. at LOWES) I used on the cab. and cleared over them with a latex spray on clear (Krylon I think). Not sure that the clear was necessary, as it is a durable paint for walls and such, just hit it with a couple coats to be sure. In the head of the game it shouldn't get much wear...
