I'm not in a position to check my other ships with ship kits. The Asp Explorer has seen a massive improvement though. When paint was worn, parts started to look very out of place and eventually a dull metallic gray that didn't match.
In 2.3 pieces are now worn and match properly.
As you can see, this is what my Asp Explorer looked like when I departed for Distant Stars.
And how she looks now at 0% on paint with the 2.3 fixes.
My Cobra Mk III enroute to Jaques during the CC Expedition in 2.2.
What she looked like just before the ship kit parts turned dull metallic gray. Notice the pods, tail and wing.
And how she looked when I finally landed. I forget the exact paint degredation level, but it wasn't 0%. Think it was around 30% or so.
Wished I could check my Vulture. That one had some odd issues with various pieces with certain paint schemes, even at 100%. It wasn't paint or decal friendly.
