I would certainly give it a try but I'm pretty cheap. I have repaired two truck transfer case oil pump wear through holes with JB weld and fiberglass cloth, I had 200000 km on the one repair when I sold the truck (more km than at failure) and 150000 km on the one I am still driving. Clean up good to bare aluminum and use brake clean to ensure a clean surface and empregnate the cloth with Jb weld and apply. Let dry, clean up the bumps and build up a few layers. Good luck!
