Iv even ripped the bag off it and started again making sure to be carefull sticking it dwn to the gum but still the same my question is Is there a certain way to not get leaks or should I just get a ultra sonic detector Thanks

After contacting they explained that is vacuum film for general usage . Now I changed it and test is good. 2m fiberglass tube with polyester resin infusion one inlet at one end bottom of tube and one outlet on other end top with spiral across the tube took 30min.
