Pressure Sensitive Adhesive is only recommended when it is completely necessary. Once the film is stuck to the polish surface it cannot be removed and reused. This creates a potential and likely problem of debris adhering to the film that cannot be removed. Any debris that comes in contact with the fiber may cause a scratch. PSA will increase the cost of the lapping film.
