If anyone has recently driven past the mural and noticed white streaks on the lower right half it is because of the sealant. It was a clear coat applied in late October when the temperature was warm enough for application, but apparently the sealant didn't adhere correctly probably because it got cold soon after being applied. This doesn't mean the actual painting has been affected, just the top clear coat, and luckily it's only the bottom half as the top half was sealed in late summer before the scissor lift was returned.
Hopefully it can be fixed in the spring, and if worst comes to worst, I'll just have to repaint the lower half of the coke oven section. Though I think there is a way to remove the sealant that didn't adhere properly without any damage to the painting.
