The MOT man jus spoiled my day. Boo. She needs a hole in the chassis patching, what guage steel sheet should I for this? I was reckoning 2mm thick stuff should be about right.

Yep 2mm will be fine are you going to make the patch larger than the hole or are you gonna cut the hole square and make a patch to fit inside it. (seam welding) the latter is tidier, stronger and looks better. but it is fiddly to do.

Overlapping patch sounds like the best bet, as me welding skills ain't the best and i'd probbly use up ten reels of wire trying to do a pukka job.

Make sure you do a good job and that the weld is unbroken or the MOT monster will fail it. If you've got a stick welder I'd use that as there better on thicker metal. and you get a neater weld. which ever you use. Practise on same thickness metal to get power and feed right. tack weld patch then weld in short runs to avoid over heating and warping the metal.
