wow! Just watched the video..never seen this before. Im assuming you have used them? If so, will this fill up the hole dense enough to when i go to drill the new hole it wont just fall back out of the old hole?
I have never used the rods. I suggest lots of practice before actual repair. These rods have been around a long time under different names and sellers.
I first saw this commercial on Sunday afternoon TV around 1999. This company named it Alumaloy:
