You got a good idea- painted them white really gives them eye appeal and really pulls the coon to them. One problem, it won't last. After a few coon, the traps are polished just about the nicest shiniest silver you could have- plenty of eye appeal.
So painting them white won'y hurt- but it doesn't last. I was just not having any luck on dryland locations with the brownish traps- so thats why I painted- results were almost immediate.
