Cliff, I think Peter was talking about more keeping it 'invisible" by using they grey color rather than protecting it from UV. ?I opted to get the flat black as was suggested by the hex maker.?
I did see some glow at night paint that I thought might be interesting. It would be especially exciting to see a 20 foot upside-down spider web glowing in the dark above the roof in the sky at Halloween. My husband nixed that idea.?
