I use painter's tape because it leaves no residue on my helmet.
I remove it when home, and don't really care what it looks like until I get there.
Interestingly.....the sheriff's department uses the same shade of blue and nearly the same width of strip added to their vehicles - to commemorate the loss of a deputy who was gunned down a few yrs ago as she answered a disturbance call.
A couple of times I've noticed deputies looking at me, and wondered what they were thinking.....
The smoke today made the low sun pretty weak. No tape needed.
Many mornings, if I were to dip my head to block the sun I'd be
moving outside my vision, even at 30mph.
