Theres also generally a lot more space to work in a plane Spot welds can also end up blind but I would say the painted part is the most problematic bit. And it's not worth the effort of trying to strip down the car to then put it back together again. And then be sure you got the process 100% right. Seems more likely to remove all the valuable bits of interior, engine, suspension, etc and then roll a new body. If they even bother doing that.
