Well, that didn't take as long as I thought it would.
Now the lines match the exhaust. Much better look.
I can't seem to find a way to get the ........................... rivet lines to fit without looking obviously distorted so I just deleted them.
Now I need to figure out what to do with the OD paint. For now it is random pixels. My instincts say I need to use a low-level Gaussian Blur to make them smooth out. Any thoughts?
