I have been prolonging this situation WAY too long. It has been going on for 3 years and it is my own fault. It has rust, but it is salvagable. I have a friend who worked for a International dealership and he saw this from all the state trucks. He said that the state would buy a new oil pan and have it Line-X coated, then installed. That would be a perfect fix. That is where my idea of aerosol can coating came from.
One question though, would that hurt oil cooling? I know the oil doesn't get cooled much from the oil pan, but primarily from the oil cooler. If anybody thinks this would be a poor idea, please let me know!
Would I be better off just wire brushing and rustoleum poof can?
Thanks for your time!
