I have a small area of rust forming under the passenger side tail light on my '06 (common on MINI's), and I've purchased a repair panel from AllMagAuto parts. Has anyone done this repair, and is there anything that I need to be aware of while cutting/fitting for the repair panel. I'm quite a "hands on" person (journeyman tool and die maker), but would appreciate any tips or advice from anyone who has already done this repair.
