i couldnt count how many tubes of this stuff i have used in a few different shops ive worked in. when i used to build boats and we needed backing plates for whatever it was that was being thru bolted, this was the only product in the shops. we used it to bond the deck to the hull etc, and of course we used fiber glass, but this shat is strong as shat. im not to sure how it would work on metal parts, but im sure if its prepd rite it would work. if you want something to stick, you need a CLEAN surface. and if i remember rite there is a proset epoxy called super tuff, that is well super tuff
