nice paint PIX. i dig that look. will see what me and my buddy can come up with, it will be plain and simple. nothing flashy. most likely black and bare metal. gotta figure out what type of metal swirl i want, random or those round swirls or something else.....
I did something on a 48 tank that gives a similar appearance. the tank was dented up so after i repaired it i smoothed out the bare metal on the top and made swirls, masked that off and painted the tank a muddy gold color and then cleared over it.
