I use a tube from the hardware store.  You apply it like caulk, then smoth
it out if needed using a wet finger, or slap some wax paper over it until
it dries.  If that's too thick, you could always try electrical tape, or
get some TV corona dope -- I seem to recall that's pretty much liquid
polystyrene you can brush on and let harden.
