There are lots of YT videos recommending this stuff, so I've tried it a few times now - and I've come to the conclusion that it really isn't a good idea. In normal SMD soldering you only briefly heat each pin, but with this stuff there is heat applied to all the pins at once, potentially for quite a long time. I've had lots of lifted pads and some ruined boards because of it. The only sure way I've found to remove a component with a package similar to what you show is to cut through the pins with a craft knife (score once, then slight slicing pressure on the crack to pop each pin away from the chip body. Then lift away the chip (discard), then clean off all the pads with a soldering iron followed by alcohol. It leaves a pristine board with almost no risk of damage. Of course you do need to be willing to sacrifice the chip, but in my experience the cost of a new chip is nearly always a trivial consideration compared to junking the entire board.
Why not use Kapton tape around the chip to limit the mess?
