I have some Ghia experience over the last 30 years or so. I bought this 1958 LowLight around 2003. Car came from California, supposedly the land of rust free cars. This is what was represented to me as "professional bodywork, ready for paint". Notice the 1/4" or more of bondo around the tail lights. This should just be 20 gauge sheetmetal. Here are the results of removing all the filler, welding the torn metal, a lot of hammer and dolly work. The rest of the car was similar. Took about 2 years of my time to really be ready for paint.
Personally, I'll never buy another half-a$$ worked on project again. I'd rather see all the rust and damage that I will be dealing with upfront!
