I did not notice this finish until a couple of days after I owned the bike. At first glance I thought it had something on it. Once I figured out that it was supposed to be there I liked it. Just another nuance most people wont notice. I think it is a nice touch.
Your clean gloss black looks good too! To each his/her own. Nice work!
Flat black is too easily marked/scratched/chipped....which is why most plastics like this aren't done with a painted finish.
I almost went white, but chickened out even tho' there was a very good match available.
I just got off of the phone with the Chairman of Honda Motors Corp. Didn't understand a damm thing he said, I don't speak Japanese. However I Googled the design and it is a map to the lost diamond mines of King Solomon.
As our great President says, this might be fake news.
