rusted

anbody want to enlighten me to the best method for repairing them to near mint condition? im unsure about what to do exactly i.e fibreglass edges? :shrug:

Utter nightmare, anything on the outside of my car (unless it's painted in the car's paint of course) - is rusted. Im talking in the way of NUMBER PLATE screw lights [:@]. And the black trim on the back needs to come off soon to make way for a reflective red one. Any ideas how to tackle this...

as the title suggest, ive got a problem with rusty rear arches. im worried that they are beyond rubbing down, filling and spraying. does anybody know if you can get replacement arch panels? if so where from? any body else had to do theres? cheers
