Interesting thread this and is exactly the reason why I laugh when I see cammoflaged torches, wallets and zippos lighters for sale.
A coulpe of years ago my step dad bought me 12 arrows for christmas, they're fibreglass cheapy ones but good enough for what I wanted to do with them. So I looked at these lovely new and very black arrows and figured, at worst I'd get to shoot each of them once and that would be it. They'd be lost forever.(Assuming I missed the target of course)
So I bought some orange flourescent paint and the proper undercoat. So now they're eye-smartingly bright orange and I have fired them a lot more than once each. Later I found a roll of tape that works like car number plates and really lights up when a torch beam hits it, which is just as well as I was target practicing in the valley opposte me and lost an arrow, somehow, despite the oragne day glo. Waited a bit until it got to dusk and went back with a torch and found it easy peasy The inch band near the fletching lit up like a beacon, which was the ony thing sticking out of the undergrowth.
Good lesson for all to learn making your valuables less likly to get lost by making them visible.
Made me wince reading in this thread about what's been lost by members. Can't be easy not spending time regretting it either.
Thanks for the warning.
