Can anyone tell me what can be used to repair an approximately 4 inch crack (midline front to back) in blue tint acrylic roof panel of 1985 model. I have found many vendors that want to sell me a new top, but I can not justify the costs as it is not leaking at this point. I want to repair for aesthetic reasons.

Thank you

You mind posting a photo? Have a couple ideas but would like to see the shade of blue.
