As I mentioned previously, I just purchased my first tube of JB Weld to fill some holes in my trick skis. My dremel tool cut through it like butter and it was pretty easy to file and sand it smooth. That being said, I would only use JB weld on an engine block in an emergency case to get me from point A to B. Then I would pull the engine and have it repaired or replaced.
