This product is used to eliminate white spots on glass film, etc., that won't adhere, as shown in photos 3-6, by applying the repair liquid. Cut the tip of the product with scissors before use. After use, you can efficiently use the product to the end by sealing it with tape. Photo 3) Condition before repair Photo 4) Photo of repair liquid being applied to the white, raised area Photo 5) It's okay if the repair liquid overflows. However, be careful with speaker holes, etc. Photo 6) This is complete after wiping it off. Recommended for these situations: ○ Edges of glass film no longer adhere due to deterioration. ○ White spots are present further inside the edge of a glass film (black or other colors) and won't adhere even when pressed. ○ White areas that won't adhere remain even after the film has just been applied. Not recommended for: ● Glass films that only adhere on the outer edges, not the entire surface. ● Areas where the non-adhering repair area is too large. ● Glass films that are warped or deformed. ● Plastic films (repairability unknown). Please feel free to ask any questions. I will answer them as best I can. Note: Repair may not always be possible depending on the condition of the glass film, so please understand this before purchasing.
