Sheet metal pinch clamps (?)

Just thought I would chime in here with some of our experience.

MIG hates magnets too by the way! Haven't you found this Greg? I have never ever had luck with magnets!

I second the cleko/strap method. We made a ton of 1/8 one inch straps with two holes, and you span the gap with clekos. Usually though, we don't try and cut the hole or panel off and fit the other piece or patch to it, as it is a pain. Simply overlap the entire panel you are trying to flush in, cleko it down the seam, and make a cut through both layers with a super thin cutoff disc. go about 8 inches, peel back the outer and inner strip that is cut off, and the panel lays in perfectly flush and ready to tack. Just dont go close to the end of your cut, always cut further.

you will like this method I promise!
