Rear Panel Repair

I have some damage to the rear side panel,about 6 inches from where it meets the corner panel with the light cluster.
I've had a look behind the side upholstery but it's double skinned so can't get at it to knock the damage out.
I see some screws that appear on the inside edge of the corner panel where the door closes to.
Does anybody know if I take these out can I remove the corner panel and maybe be able to get to the damage between the skins without wrecking anything?

replace the panel, screwed by the door as you said and pop riveted or just skim it, bear in mind its ally so it does have a lot more flex than steel panels. fibreglass is probably your best bet with a small skim of filler. either way your into paint and very expensive if you cant do it yourself and to get a good match or its gonna stick out like a saw thumb to anyone with an eye for things like this.

could try the old series or defender approach and rivet a bit of chequer plate over it!
dont think you would get a very good match spraying with tins- could end up looking worse and dont even think about diy if its metallic!
i would let the professionals do it or live with it if it aint to bad
