that looks awesome! apart from the colour (not to my paticular taste). how is that done and how do you then open the boot???
As above for getting into the boot. As for how it's done, there are a couple of ways but I'd personally remove the lock mechanism, weld a sheet of metal over the hole, smooth it and all weld marks, fill any odd surfaces to get it totally flush and then prime, paint and you're done.
It's a lot of work, but not a big deal for somebody who knows what they're doing. Might cost a few quid though!
