Hi,
I've plated over a hole in the floor of my old cav. cut all the rust out but fitted slightly oversize plate from the inside - needed to hammer into shape as I went so much easier to fit oversize plate to inside. Obviously the overlap is visible from underneath, do I need to now weld this up on the underside of the car or can I just seam seal the gap between floor and new plate to be good enough for MOT.
Thanks
Jim
