Only pinholes and small cracks that occur on a flat surface (in welds, joints and edges) can be glued with a higher percentage of success. If the defect is on a suede surface, then before gluing, remove the suede from the patch area with a fine emery cloth and degrease the area with white spirit. Then apply the patch. You can use any PVC patch and any PVC glue for gluing. Intex does not manufacture PVC adhesives.
