After a few weeks of owning the Barrichello I thought it was useful to do a quick side by side of the Ceramic finishing of the Barrichello (produced over a decade ago) vs the newer Perpetual ceramic.
To me, it's clear that there has clearly been an improvement in AP's expert finishing of ceramic pieces - don't know if this is the best photo to compare but it's a start. What you can clearly see is that for the perpetual you can see the finishing to be the same as the RG portion of the Barrichello.
I'm hoping for more new pieces leveraging this expertise! I'm wondering if others have noticed this too?
