Leaking Coolant Issue

Last Decemeber I replaced my water pump after I was no longer getting heat and my 2004 Jeep grand cherokee overheated. I had not ever replaced a water pump so I printed out instructions and followed them exactly. It seemed to work.

Then a couple months later I was leaking coolant and had to fill her up again. That coolant lasted a few more weeks. I took the water pump back off and noticed that the gasket I had used was destroyed...

So I scraped it off and used some red RTV silicone to make my own gasket. Two months later I was running out of coolant again.

I again sealed my water pump a couple weeks ago. This time I bought some RTV Silicone designed for water pumps, thinking that I had just used the wrong stuff. A week later, my temp gauge was bouncing in and out of the danger zone and I was forced to stop at a shady gas station in the bad part of Chicago.

I read on the water gasket RTV (after I had applied it) that I was suppose to let it sit for 24 hours. I let it sit for maybe 3, because I had to go to work. I figured that this had to be the problem with my last attempt.

I decided to do it right this time, so I bought extra water gasket RTV and I plan to use a layer of it, followed by a brand new gasket, covered with more silicone.

Before starting just now I decided to take a peak to make sure that it was indeed my water pump leaking. There is a large amount of dried coolant around the pump, but I noticed that there is a significant amount on my radiator as well. I have included some pictures. Im no expert, so I'm wondering if I could have a leak in my radiator. Or is the coolant just spraying to that location from the water pump?
