So I parked up for a stroll on the beach and when I came back to the car I see a nice bend in the door.
As you can see the bend is a bit of an eye sore.
Out with some masking tape to line up the repair area, a rubber ended G-clamp so I don't do any damage, a hammer (cushioned with a rubber bung) and finally some microfibre cloths and polish when everything is done!
I removed the plastic trim on the inside of the door so I had just bare meal to squeeze. I taped off the area in question and gently forced the G-Clamp closed until it lined up. Pretty much got it after the first attempt but went back two more times to make 100% sure. Fortunately there was no paintwork damage, cracking or bending so I removed the tape and voila!
