That must not be from the vinyl glue like they sell at Seattle Fabrics which I used which and I think is the same as Vyna Bond glue that I used on an inflatable boat patch. I think I read somewhere that back then FWC tried using the velcro with the adhesive backing (big mistake). If the black goo is coming from around where the velcro is that might be the problem. The vinyl glue gives a clean and very durable bond.
