Robert,
Fairly common - as the sealant around the taillights gets old, some water
can get in. The water will also rust the taillight fixtures - leading to
all sorts of electrical hijinks. The best solution is to go to an
Automotive Paint place and get a tube of Urethane sealant, remove the
taillights, clean the old sealant off and use the urethane. If the present
owner is using a Home Depot solution to the leak, maybe you should take a
closer look into the care of the car (ie - oil changes, engine compression,
what type of oil filter are they using, if there's a K&N air filter in....).
It might also have been in an accident, breaking the seal around the light
(or necessitating its replacement).
Cheers!
