a little repair I did a few years ago (passed two MOT's after these repairs- the inspector didn't even spot the sills had been repaired [

] )
Grind off the stone chip and the damage is much worse that it first appeared.
Oh dear, more rust inside!
Where it is on the car
Before making repair sections, make templates out of cardboard
transfer shape onto 0.9mm mild steel CR4 grade
patch cut out with aviation snips- accuracy it vital!
folds put in with a hammer and vice (no folding machine at home)
Inner sill repair section tacked in
all inner repair sections in place
Inside of sill galve primed to simulate original galvanised protection
Outer sill patches being welded on
Outer sill repairs in place and welds ground smooth
Zinc primed, seam sealed and stonechip coated and the repair is almost invisible
Primed in cellulose and painted in Guards Red cellulose top coat (done at home so no 2-pack)
The colour match was very good with the original paint and the join between repair and original was done along the libe where the stone chip coating finishes.
Sorry for all the pics, but this gives you an idea that decent localised repairs are possible to a 944 sill and possibly more economic (I still have loads of paint left so the repair only cost me about £20- £30 in materials) [
