We used to slather on a thin layer of RTV3145 (obtained cheaply, thanks to the DOD local auctions) on cups until we could get a replacement. I went on a service call one time to find a cup in a 60's Magnavox we had layered with RTV, still holding up after 6 or 7 years. At the time, gray RTV was a rarity, and most of the stuff sold commercially was either white or black, so seeing a gray-RTV-slathered cup told me instantly it was one of our patch jobs.
Good enough for flybacks, good enough for HV cups. IIRC, RTV3145 has a dielectric strength of about 2KV/mil or so. Try to dig out any carbon traces (if present) before applying the RTV, and keep it thin - you can always add easily. Cheers,
