Trunk Paint?

I have a pretty decent 74 dart Sport that I am working on right now.

The trunk has some surface rust that I am repairing with a wire wheel and then applying POR to it.

I would like to apply some type of paint like the roughend black and grey speckled stuff.

I am not interested in OEM stuff at this time.

Something to make things look better is all until I repaint the whole car in a year or two.

Any ideas or links to kits?

Thanks, ROB
