Upgrade for rubber differential plug?

Upgrade for rubber differential plug?
Purchased my truck recently and have some weeping from the rubber differential plug. I've done some searching and seems like this is pretty common.
My question is, does anyone happen to make an aftermarket upgrade to correct this monument to Detroit engineering? My concern is that since fluid is getting out, moisture has gotten in. I have on my to-do list pulling the cover off to drain and replace the gear oil. Maybe an affordable rear differential cover that comes with a traditional pipe-thread plug? Or a bung that you can purchase and weld on to the stock cover?
If the answer is 'no' to the above, is it possible to just augment the plug with some gasket maker to make a better seal?
Thanks.

I know that when I do my diffs, I take the cover off to drain them, the fill with the fill plug on top. The only down side to this is that you really cant drive for the next 12-24 hours after if you use RTV to make a seal.

i let mine sit an hour and she was good, gone offroading many times since...no water....
but my plug has recently started to weep as well, get a new rubber plug, its the best bet.
