I put some photofinish baits up on the roof of my shop for one straight week, just to see the effects from the sun. I had heard rumors that this and that would happen to photofinish baits, if left in the sun. It was 100-106 degrees all week and all looked the same, as the day I first put them up there, when I took them down at day 7. All where cleared with Devcon or Bob Smith's epoxy.
