So here we are; the dreaded rust on rear e36 arches. And I know, this one (drivers side) is rather bad.
Someone long before i bought the car has repaired a dent in the back quarter panel, as can be seen from the pic the approach of filler/primer/paint/more filler(??)/primer/paint, the 'repair' hasnt lasted. I am thinking of getting someone cut out the really bad bit and weld in an arch repair panel (similar to http://cgi.ebay.co.uk/BMW-E36-90-98-...3%3A1|294%3A50.)
However my main question is, is the long crack i have circled strucurally inportant? And does it look like it is a stage too far to have anything done to it?
Ive done a few sprays on cars, but im out my depth here, any help/advice greatly appreciated
