Sometimes the stop-leak stuff actually works. AlumaSeal was the best you could get since forever, but it appears to have been discontinued by the manufacturer. Bar's Leaks was another good one and it's still around.
The lift strut that Pops broke a few weeks ago came home from the welding shop on Friday. I put it back on the tractor yesterday morning so now he can get back to mowing in between naps.
The local auto parts store had some liquid stop leak and then in back of it, little plastic vials with silver powder/flakes inside but I don’t recall if it was AlumaSeal but I agree, the best. It worked for quite a while and then it started leaking again. Maybe some more found it’s way to the hole.
