Alas, Jubilee is no more.....
It was a Johnson product. Until recently you could still get the aerosol.
I am a believer in Glass Wax. It was recently discontinued as well.
When I went searching for a knockoff, I remember seeing (although I can't remember where) a Jubilee knockoff with one of those bizarro knockoff names (it was "Jubilation" or something lol), along with the Glass wax knockoff). This Jubilee clone was the liquid in the plastic bottle, the one I used to use and like.
If I remember, I'll post back (maybe it was fiveandten.com or something?)
