Rear Main Seal

My oil pan had a pin hole leak in it for some reason. What I did was drained the oil. Then I used a wire wheel on a drill and took all the paint off of that area of the oil pan. Then used fresh paper towls and Brake Parts Cleaner to wipe it off. Put the JB Weld on it and let it sit a few days. Then I sanded it a little bit (don't get too ambitious with the sanding) then I painted the area with engine paint. Filled it with oil and its been bone dry for years now. I picked up a nice used oil pan off ebay so if I ever take it off again I'll replace it then.
