Think this it
He got through it, but I would have gotten fired for doing it like that at most, but not all places I've worked at. He didn't have much blend room for what appears to be pearl white.
I've fixed plenty of bullet holes. 9 out of 10 times you can hammer and dolly the holes just about back closed instead of leaving the wadded up metal inside the door and just welding across it. You can't back up the weld with a piece of copper if it's like shrapnel inside.
A screw hole or something sure but when you put on tack on top another across a large hole it's not that hard to end up with an air pocket/pinhole in the welding that you may not see when grinding it. Get it painted, put together, park it outside in the sun and opps there's a blister in the paint right at the repair a couple hours later. Let's do it again.
In his defense this may have been a cash job where you don't have an insurance company looking over our shoulder scrutinizing repair methods or quality and just did the bare minimum, quickest way possible, to get it out the door.
5 minutes trimming a piece to fit the hole , trim the hole if you have to, weld the perimeter, and be done. No bird turd porcupine looking welds on the inside. Less chance for problems on the outside.
