Looks like a '65 Satellite, shows up on my monitor like D, the light blue metallic.
FT says K, light turquoise metallic; can't quite make out interior code, is that B, like blue ?
I'm going by memory on those codes, correct me if I'm wrong.
But to answer the question, looks like glue residue on roof.
VT could have been added, not sure of they were called out on FT in that period, that was early days for VT.
