Strange thing...i had a multivario bag shipped to me, in great condition. However, it was packed in styro peanuts, and the foam on the bottom of the bag disintegrated (heat/condensation?) like chocolate cake.

I did my best to scrape it all off, but now there are some holes/tears in the vinyl and tons of old glue. Am i better off taking it to get a new piece stitched in with foam, at an upholstery place? Or can i just patch it and glue a new piece of close-cell foam in place? I would think glue-glue isn't a good bond. Thanks
