Looks pretty close to what my brother is doing up for me. I plan to glass-bead-blast the inside of the lettering to remove the machining marks and more closely approximate the original sand cast pieces.
I polished with White clay bar, then with Red Clay and finally with mothers. The paint was Rustoleum sprayed in the cap, soaked a soft bristol brush and flooded it several times. You can still see some etching but then again, I'm content! :-)
