I was cleaning my glass hole box and realized that the frame looks like it has a clean crack straight down. I felt around the glass and can't feel a crack or anything on the glass or around the bulkhead. Should I need to be concerned.
What I'd do is pick up some JB Weld (Walmart automotive area....about 5 or 6 bucks) and mix up some and fill the crack. I don't know if this epoxy would do much, except to make me feel like I did something.
It's hard to tell from the picture with all that blue...but this is the edge molding around the top of the tank....outer edge?
Use Weldon 16 it should hold well
