  • Outline the hole with a marker and cut it away carefully with a razor blade. Ensure that you don’t cut deeper into the frame than the vinyl.
  • Again, measure the area to be repaired. Cut two patches with one slightly longer than the repair area and the other that fits the space exactly.
  • Insert the longer patch inside the hole and, then wearing the gloves, use the PVC gap filler to secure it in place on the inside of the hole. The gap filler should be applied to the outside face of the interior patch as well.
  • Now, firmly press down the exact match patch using the included tool. Seal the edges with more gap filler and wipe away any excess using the tool.
  • Let it dry for 24 hours.
  • Carefully scrape any excess gap filler away using a razor blade. Sand smooth.
  • Buff any visual signs of the hole and excess gap filler away using a scratch remover compound. Polish and clean.
