It's Not A Wrap - Boat Stored Indoors!

what does that do @Handymans342

Handymans342

Seals it.

But it takes away the bond so it is ungrounded....

You can also use petroleum jelly, or grease

The drain plug isn't grounded anyway Ray just like all the thru hulls. At least on my boat nothing is bonded

If you want to "grease" an electrical connection properly,  IMO,  may I recommend dielectric "grease". It will not interfere with electrical conductivity,  in fact it should enhance it.

I remove my drain plug every time I pull the boat since I only leave it in the water if I'm going to use it multiple days in a row (I have a slip and a rack at my marina).  Mine is brass I think (lighter color and more shiny than his).. should I be using something on it?  I usually have no water, or maybe a tiny bit in the bilge when I do remove it. -=Mike G.

I use a couple of wraps of Teflon tape to ensure no leaking easy removal but that's for a yearly removal.  If you're removing the plug frequently I don't see an issue as long as you're careful not to cross thread it.
