Hi all! I’m new to the site and have a question about my “new to me” ride. 2003 NB convertible in harvest moon. I have a black top that has some abrasions on it. Most the top is nice but it’s like someone rubbed a little bit of sand paper in spots and I also have a couple of spot that the canvas has loose threads and I don’t want them to start unraveling to make a hole. Is there any product to stop this from happening?
