Jester-
I was actually talking about the inside of the radiator. My old motor had a lot of corrosion on the inside of the coolant jackets from the previous California owner running straight water in it. I finally got tired of the cooling issues and took it to the radiator shop where they took it apart and cleaned it up just like new.

But Jester did make an excellent point. If you live anywhere like Illinois, driving threw the country for a summer here, them ole bugs outta the corn fields will fill the front of the radiators real quick.
