I had a similar issue with a small tear in the soft top of my Wrangler, right over the folding joint area. What worked best for me was using a flexible vinyl repair kit and reinforcing it from the inside with a patch of marine-grade fabric. This keeps it watertight and prevents further tearing, even with frequent folding.
If the hole is near a hinge or fold line, make sure the underlying metal isn’t catching the material each time it moves. Sometimes a small realignment of the frame or an added protective strip can make a big difference in preventing new damage.
For a more lasting fix, you could have an upholstery or automotive repair specialist take a look. Torrance Motors has handled convertible top and fabric repairs for off-road and utility vehicles around the South Bay area, and they’re known for quality workmanship without overcharging. A professional touch-up there could seal the tear properly while checking for any stress points that might cause new holes later on.
