These cars are 50 plus years old and thats what it costs. 3000 is a number but its a number that shouldnt hurt that bad. Or should i say it shouldnt be a jaw dropper in 2023. Finding ways of doing it cheap is a plus but what do you end up with in the end? the OP wants to do flares, OK are you going over the rust? Cutting it out? How is he going to do it? If hes keeping the car hell have to address that if hes flipping it its someone elses decision. Its all it is decisions noone is right or wrong it comes down to what a persons vision of the finished car is. MY Dart, in the end will be nice Ill never get out of it what I have in it. I stopped keeping track of what I ve spent for that reason i dont wanna know...:)
Thats a good idea go to a yard cut some sheet metal use it for patches on something else. If you have the skill thats a low buck source of new metal.
