Not completely without precedent. I have some old Mullard EF37A's that were painted with red conductive paint from the factory. Other European tubes have similar coatings. Supposed to help with shielding.
That's not to say that the OP's 'tube paint' is the same stuff, or even anything worthwhile. Just that (like everything) it's been done before.
