Metal Bonding Questions

I've been using Duramix for years,but since 3M bought Duramix out,I switched to SEM, I've tried Fuzor and was not impressed at all, so I use SEM, the stuff works great,especially when used to replace roof skins, floors,quarters. It nearly eliminates the welding,grinding and cleaning up the welds,

Keep in mind, that you must weld corners on each panel you're bonding,and when replacing quarters or roof skin,the seam on sail panel must be welded,instead of glued, because it will show after a while,it won't crack, but seam will be visible,
