ive got an old nissan micra and the rear wheelarches are rusting quite badly. whats the best way to fix it?

do you have a welder?

How bad is it really, is the whole inner lip gone? If so and you don't have a welder then you can pop rivet a new panel on and then use Davids P40 filler to bond an bend the repair on. Then spray waxoil into the inner space behind the arch to prevent it rusting again. It'll take time and patience to do a good job

we actually have a craftsman on this site who specialises in micra repairs...he shall remain nameless though
