 Ray,I Guess All of My Engendering Training Must Be in for nought, If I remember 99% of the Bulk Head Feed Troughs are Not (AL) but some form of Plated "Metal" Alloy.  So lets see AL+H2O+"Metal"  Over Time Will Result in ELECTROLYSIS which in the Radio World Adds some Interesting NOISE Products .Yes, Clear Silicone Will protect for a short time but in the Florida Environment with Heating and Cooling cycles Plus UV will separate and actually form capillary action.  Thus My recommendation of Coax Seal at a minimum and the the True Professional  Method is to use a Plastic Sleeve for the Bulk Head Feed Trough and then the Coax Seal.

 Steve...
It looks like Marty's birdcage is made of aluminum, so corrosion where the connector is bolted shouldn't be a problem.   But if that's a concern, a little clear silicone caulk should seal it up.
I was specifically referring to covering and protecting the "guts" of the  female SO-239 bulkhead connector.  
Those little plastic caps will keep the inside of the bulkhead connector nice and shiny.  But, as I write this, I  occurs to me that a little squirt of Pro-Gold every now and then wouldn't hurt either.

 Asides the Plastic Caps Caps, When You Do this type of installation you should  Use "Coax Seal" around the entry points thus preventing  Water Entry by wind driven rain (Yes It Will Get In) and Then you get Interior "CORROSION".73'sSteveAB2ET

 To piggyback on Marty’s excellent idea…DX Engineering (And other vendors I’m sure) sell plastic caps that will fit over that bulkhead connector and will help prevent any excess corrosion.
