Street Rodder mag.(I think) did an article about faux finish and even showed a '32 truck being "rusted". I don't remember the issue num., but you might contact them for a back issue. An artist here in Ft. Worth area did a glass car complete with straw hanging out of different places mismatched frt. and rr. wheels, heck he even won a few pick's at some of the runs. His last is Anderson, but don't remember any address, he does art work etc. for a living.
I agree with some of the other greybeards, we had primered cars in the past, but we all wanted paint and interior (though few succeded).
