A 1974 Duster - My 2nd one, 41 years later!
Well I would say the body lines are affected and compromised, it would take a pro to sculp the panel back to acceptable standards. I will still have to cut the bit of rust from the bottom corner. I have a pro autobody guy coming to tell me what he thinks. I am not afraid of installing a new 1/4. Welder and spot weld cutting bit are standing by ready for the word. Anyway, while I wait a Pro's decision on the 1/4 panel I will continue to get the car straight, in primer, and ready to paint. Removed the windshield today to inspect windshield channel and clean it all up. Only found very very minor surface rust, lots of black sticky crap. I will scrap it all out and corroseal it.
