Goodmark vs no name metal?

[coupe33]

I have always been told and find it true that the quality of metal/iron that other countries have available to them does not have as good of alloy to it, now i know that you can add to the mix when creating steel but as said above the cost out wieghs the return. i have installed countless repop pieces of sheetmetal and its always a coin toss, some fit very well with little to no modification others well lests just say it looked like a fender or quarter but thats all it had going for it. its always frustrating that when you buy repop you could still be in for as much work as trying to repair or find oem metal. And i can tell you it does not matter who you buy from or how much you pay its always the same result. who ever said it all comes from the same plant could very well have nailed it.
