You can use a piece of brass (I use a hammer head) to hold over the back side of a trim hole, rust spot, crack, etc...then weld up the other side. Once the weld starts to cool it will pop loose from the brass, I've done holes as large as 1/2" and it works great.
I ground the hammer head slightly concave so the patch will be thick enough to grind down.
