Some of the threads on my top have become unseamed in the rear, around the window. I plan on getting a new top later on, but not right now. Is there some sort of glue or something that I can put between the cloth (where it was sewed together) in the mean time? Where can I get it? Thanks.
You might ask a local upholstery or top shop what they would suggest. I'm sure they have top adhesive/sealant in their shop. They may be able to provide you with a temporary fix until you get a new top.
Here's a product you might try looking into and see if it meets your application. Speed-Sew
