Just failed MOT on sills

[mushroom]

Do I have to replace the whole sills ( inner and outer) of can I patch the old ones ?
On MOT sheet it just says rear part corroded
If so where can I get patches or do I have to make my own ?

[purplechugster]

Which bit is corroded?

I had an MOT failure on the sills as it was near where the seat belt bracket is

...But I got it welded for negligible money and it passed fine

[mushroom]

it's the bit near the rear suspension mountings

I patched a couple of small holes on mine (right next to the rear jacking points - as long as the welds are continuous and it ends up solid and neatish it should be fine - mine was!
