Nice little texture, my only crit would be that paint is very singular in how its been worn. Its pretty much on or off with the same brush used to do it. I personally would go and get a scratch texture and use a lighten or darken overlay on it, mess with the levels a bit then use that in your mask channel. Basiclly meaning, get a complicated texture, level it to find the areas you want to keep and might work well, merge it down then greyscale it, crank up the levels again so your getting a black and white effect but still have some gradient. Then throw it in the mask of your paint, add a outer noise to that mask giving it a bit more of a broken effect. Then just go back to the original scratch texture and play with it until you feel your using the amount of surface detail you need.

Hmmm, I hope that made sense...

EDIT: Oh ye and a nice way to do metal also is to put most of its detail in the specular map, rather than the diffuse. Although its obvious the diffuse is going to need some detail. Just give your specular high contrast.

EDIT2: Forgot to add, work on those painted stripes as well. They look very line tool!
