Convertible tops are commonly made of vinyl since the material is waterproof and does not tear easily. It is possible, however, for the vinyl top or the vinyl window within the top to rip if a sharp object falls onto the surface. You can patch the hole using a vinyl sub-patch and a few other materials needed to complete the repair.
Wash the vinyl surface for the best repair. Mix mild detergent with warm water on a sponge, and give the surface a gentle rub down to remove dirt and build-up. Dry it completely with a soft cloth.
Cut off any frayed edges surrounding the hole with scissors.
Measure the length and width of the hole so you know how large your patch needs to be.
Cut the vinyl patch to be at least 1 inch wider and longer than the size of the hole.
Apply the vinyl adhesive to one side of the patch using a paint brush or the provided applicator if one comes with the adhesive.
Turn the patch adhesive side down, place it over the hole and press firmly for one minute until it begins to dry without slipping.
Allow 24 hours for the adhesive to fully dry and bond with the vinyl window top.
