Smith & Nephew 5466000040 Opsite Flexifix 2 Inch x 11 Yards Transparent Film Dressing

Regarding leaking, try putting down Opsite Flexifix first. Before I started using this as an under patch, my pods would leak. After, not a single one. (I’ve heard Tegaderm patches also work.)

Almost same, I use Opsite Flexifix 2” wide tape Smith & Nephew. Available on Amazon: https://a.co/d/0hMwvKnt I never have this stuff come off, and I have had zero leaks since I started using it over two years ago.
