Drip, Drip, Drip water torture!!!

Recently my MKIV has developed a very small but annoying leak on the lower radiator house outlet (see picture).
I have tried different type of hoses, clamps, etc and nothing seems to stop the leak.
My latest effort was to put RTV around the aluminum outlet, then slip on the hose adapter provided and then a silicone hose over that.
The leak is always occurring on the bottom of the radiator outlet. I have not observed any cracks or holes in the aluminum outlet, but maybe it is out of round?

Any suggestions would be appreciated.

The picture below shows the RTV that was squished out when I slid the hose on so I simply smeared it around the bottom. Not the prettiest and I realize that portion is not providing any leak stoppage. šŸ˜Š
