I just received my '64 1/2 driveshaft done by Jack at Dead Nuts On. It is bare metal, and will rust unless I coat it with something. I have clear lacquer spray, and some Boeshield Tim Lea left me after restoring my KR he liked to coat bare metal parts with. Which would be best considering I am entering it into Driven Concours at the MCA National in June? Thanks for any opinions.
