Pinhole
Also: pinhole, micro hole, thorn hole
A pinhole is a tiny hole, for example from a thorn. You fix it with a drop of liquid PU or a small patch.
For small holes, Anfibio names liquid PU such as Aquasure, Seam Grip or Stormsure, which needs about 12 hours to cure. Alpacka also mentions a tape patch of about 2.5 cm or Aquaseal UV, which cures in the sun within seconds. It's important to apply thinly; thick layers come off more easily.
