I did not want to hijack the other Cast Iron thread so I will ask this here.

I bought an inexpensive cast iron fish cooker, consisting of large pot with lid and a propane burner. The first time I tried to use it I filled it about half way up with canola oil and lit the flame under it. As soon as the oil got warm, not even hot, there was a spot about 3 inches in diameter on the side of the pot that started seeping oil THROUGH the cast iron. It, of course ran down into the flame and flared off. I got the burner turned off and watched as the oil just seeped through the side in that one place. As the oil cooled it stopped flowing. I relegated the pot to the corner of the garage where it lives today. Can it be fixed, or should it just continue to hold the small parts of other projects as it does today?
