you need to cut it back to, as you put it, good metal, thats why it's called good metal!
do the job right or don't do it at all!
I fiddled around with a variety of different attempts to do this job quick and easy and none of them worked, not even the copper bar trick, so I ended up cutting back to good metal and doing the job right
. Still found that welding the patches in with a flux core mig was a challenge but worked at it until I found a method that was successful. As you can imagine that entailed real short bursts...bzt, bzt, bzt, bzt.....as I moved around the patch from side to side to side.
It was 34 degrees C here today (that is 93 degrees F for those of you that aren't ambidextrous!!), which is pretty warm for Canucks, so I was wearing shorts in the garage as I was welding. As I was kneeling on the concrete, leaning in the door to weld, I put some cardboard down to pad my knees. Well, you can guess what happened as I concentrated on welding the patch. Luckily I smelled the fire before it got to me, didn't even lose any hair off my legs. Note to self...find something fireproof to kneel on when its hot out.
