Just get it painted...... a good paint job can look very like the real thing.
cutting, rivetting, sealing testing for leaks, and then re-sealing will take time, and money......
and I didnt think you were spending lots on your airhead JD.
or....Paint, and rivet heads stuck on......
choice is yours,

paint wont give me the look i want ,allthough i dont think its practical to do for me ,as my ideas sometimes out weigh my ability ,stil no harm in trying or asking
