Radio Antenna

[Brucethept]

I have a 2009 FC with a radio antenna located on the top of the front end cap. When cleaning the roof today I noticed that there was no caulking around the base. It is clear from the discoloration on the roof that some caulking was there at some time. I don't know if this antenna was replaced at some time. It was hard to tell if the current antenna has a gasket or not.
If it requires caulking what would you recommend.
Thanks all!

I would use Acryl-R (successor to Vulkem). JC sells it as a kit with a pump that lets you lay a fine 1/16" bead - not cheap, but very good. You will probably be using it for redoing various places where the caulking needs to be redone.
