Looking to patch a load bearing torn seam on my heavy spa cover where it folds in half** A: Doubt this is what you are looking for **Q: Will this seal a small hole on an alluminum boat** A: It would but I don’t know that it would be a good long term solution. I have used a product called Mr Sticky on an aluminum boat and it worked really well **Q: Would this work in a shower tub seam** A: Might not look as smooth as caulk but it'll certainly do the job. **Q: Can this be applied under water?** A: I don't know about applying under water, but it is good to keep water out. I had water coming into my basement from a crack in my patio. Put flex tape over the cement crack outside and haven't had any more water seep into the basement and hasn't for several years. Not that pretty, but it works! ## Customer Reviews ### ⭐⭐⭐⭐⭐ used in the shower on my schoolie *by N***R on June 16, 2026* great sealer ### ⭐⭐⭐⭐⭐ Seals great! *by D***P on April 15, 2025* Excellent tape for hold and durability.
