There used to be reflective stickers you could put on your rims, back in the 80's I did that and it seemed ok.
This reflective paint is the way of the future.
A year ago I was talking with a fellow SF randonneur about reflective paint for an entire bike.
I hope this is the start of that.
I would do this in a heartbeat for my bike, my wifes bike, and my sons bike.
We live in the city and ride day and night, every day of the year.
Good job with the wheels, well thought out!
