Repairing Steel Fenders Without Warpage

Auto body panels are constructed of very thin metal, and MIG welding these parts without warpage can be very difficult. In this video Super Alloy 1 repairs a steel fender.

Our multi-metal solder will repair this fender at such a low temperature that even the paint around the hole is not affected.



  • Broadly heat the base metal when working with Super Alloy 1.
  • Super Alloy 1 can be used with propane, butane, MAPP gas, acetylene, oxyacetylene.
  • Always remember to turn the oxygen down with oxyacetylene.
  • For added warpage protection, combine with Heat Freeze Heat Paste.
