i wouldnt personally but if you do make sure u weld a plate behind it, what we did with my mates was to weld a plate on behind the hole, then weld a smaller bit in the hole so its the same level as the metal on the bootlid then fill the gap with weld and flat it back, then fill any imperfectiond as this way it wont crack, you will need a solonoid of some sort to release the boot
