Applying Stop Leak Tape

When it comes to applying Stop Leak Tape, it's essential to follow these steps to ensure a secure and effective seal, especially in New Zealand's varying weather conditions:

  1. Measure and Cut: Start by measuring the required length of Stop leak Tape. For cutting, we recommend using a razor blade for precise results.

  3. Remove Backing: Peel off the transparent backing from the tape.
  4. Apply Firm Pressure: Press the Stop leak Tape firmly onto the surface, making sure to eliminate any air pockets.
