Repairing small section of rust on the body

collision shops do not make any money on rust repair. Its all R&R and painting and thats about it. Alot of smaller shops do not want to deal with the customers because rust oftens turns out worse than what it appears on the surface. When the bill comes the customers frind they are in over their heads. In Michigan, there are a lot of hobby restorers so the rust repair work on classic cars is not in big demand for shops.
I would suggest a "night class" at a local tech-school or junior college. Or just get a cheap 110 welder and start practicing.
