You want to know why I hate silicone? Here's a ONE example:

[Casita Greg]

Just an "aside"...
Caulk, no "h" in it...

[stairman]

You know your right, Ive probably always spelled it the other way the few times Ive actually needed to spell it. Ill make a note of it.

There is a sticky rope putty that remains flexible and is easy to remove that I would recommend as a temporary fix. It is called something crack seal or draft seal, the rope is about 3/16" round sold in sheets about 8" long. Usually found in the window or insulation areas.
Sorry the brand name slips my memory banks at the moment. Red or orange package.
