I just installed a new back up camera in the 3rd brake light. the picture looks bad, but i haven't even blended it in yet. I didn't use any screws, and surely didn't puncture the aluminum housing. I installed it, drove home that night, and the next day, theres condensation underneath the glass in the housing.

the only thing i can figure out is that heat from the epoxy i used created the moisture, but it's been warm out enough that it should have evaporated somehow...

anyone have any ideas?
