Hey guys! I am new to metal body work and am not sure what to do here. I have a wire fed mig welder but I have very little experience with it. I really want to do this myself but not sure how to go about it. Here are some of my questions.
What guage metal do I need to use for the patch?
How do I make a pattern for the patch?
How do I hold the patch in place while welding it?
Do I weld it from the outside, inside or both?
