powder coat hairline cracks

[avantey]

I just got my first piece back from the PC'er. It is beautiful except for the bottom. There are what appear to be scratches on it that the guy said are actually hairline cracks in the metal that just come through on old metal like this. Is this true or can I buff them out?

Als my body man buddy said that PC is like procelain since it is hard and baked on. Is this a lso true in terms of hardness, gloss retention, etc.?

thanks- Bill
