i drive an '04 Grand Prix GT. lately i have been noticing that after a rain my car leaks between the two interior lights in the front. i believe that this is due to the radio antenna (located directly above leak) not being sealed properly.

is there a way that i can remove the unit that holds the interior lights to possibly apply liquid silicone around the antenna? (obviously, i don't want to do this on the outside of the car.)

i would appreciate any advice.
