Hey guys and gals
I've been doing some experimenting and here's my conclusions.
If you're having difficulty seeing your sights try this color combo, flouresent orange and flouresent green.
Now for the real tip.
I've tried model paint and special gunsight paint but the most durable "optic optimiser" that I've found is...Nail Polish.
The other finishes seem to rub off or peel off in a very short amount of time but the nail polish has now held up for weeks.
Let me know what you think.
