[Connor]

you would have to get rid off ALL the rust anyway to avoid its return

The rust is cut out, hence the two gaps

all as your doing is skimming the edges were you cut so there straight not exactly going to hack the lot out are you.

See how much repair panels are - the hatch rear arch ones are only about £8-10 I think?! If they're similarly cheap for the saloon you might as well get some and just cut out the bits you need. At least it'll be less effort in bending the plates to fit the shape of the arch.

Just put a proper arch repair panel in, theyre cheap and it'll save doing the job again which you will end up doing if you botch it as the rust will end up pushing back through within a few months.
