My torch has a barnacle growing on the top, right next to the mouth. I have poked it and cleaned out the inside stuff. To prevent any bugs from living inside the empty barnacle shell, I sealed the top with coral glue, with the middle still being hollow. I want to confirm whether this is a bad move to glue it up -- it traps some water inside the shell. If I have not killed/cleaned the barnacle properly, would it cultivate bacterial growth inside?
