This topic is about finding a colostomy pouching system that provides a reliable seal, staying securely attached for several days without the worry of leaks. Mike is looking for recommendations on products or techniques that can offer a stronger and longer-lasting seal, especially after exercise or an active day. Here are some suggestions and insights from others who have faced similar challenges:

1. Hollister Systems
- Users report 6-to-10-day wear with options like the one-piece soft convex and two-piece systems with cloth-edged adhesive, as well as the Hollister CeraPlus #8958.
- Performance can be enhanced with accessories like the Hollister CeraRing barrier ring, Salts rings, flange extenders, or pink zinc tape.
- The soft, comfortable cloth adhesive is often preferred over Coloplast for its reliability.

2. Coloplast Tips and Set-ups
- The Coloplast SenSura Mio Convex 2-piece can be combined with Coloplast Brava paste or Brava strip paste, 3M Cavilon No-Sting Barrier Film wipes, and a small Coloplast SenSura Mio belt. A Nu-Hope belt can be added for heavy lifting.
- Some users find that wearing a hernia belt immediately after application helps press the wafer firmly in place, potentially eliminating the need for extra barrier strips.

3. ConvaTec Options
- The ConvaTec Natura 2-piece system, when paired with Coloplast Brava strip paste, offers 7-day wear for some users.
- Another combination is the ConvaTec ActiveLife with a Hollister CeraRing.

4. Accessory Rings and Tapes
- Salts rings are highly recommended for their strong seal, often lasting over 10 days.
- Flange extenders and pink zinc tape can add extra security around the edges.

5. Application Techniques
- Warm the flange or wafer with a blow dryer or hair dryer on a warm setting before applying.
- Ensure the skin is completely dry, then hold the wafer down firmly with warm hands for 2 minutes. Some users lie down for 30 minutes after application.
- Convex bases can improve fit and extend wear time, especially if the stoma is flush or retracted.
- Higher-liquid output may shorten wear time, requiring more frequent changes.

6. Support Belts
- Hernia belts, Coloplast belts, and Nu-Hope belts can improve adhesion by providing continuous pressure. Adding foam padding may enhance comfort.

7. General Observation
- Since individual skin and stoma differences affect results, trying various brands like Coloplast, Hollister, and ConvaTec, along with the mentioned accessories and techniques, can help find the most reliable personal solution.
