## Questions & Answers

**Q: would this be OK to stick my satellite dish to the top of my motor-home without screws?**
A: It's a good product but I would not trust it for that, use it along with the screws, just to be on the safe side. Is there not a plate with the dish that you could fix on permanently so that you could easily remove the dish?

**Q: Dear,

May i know the best before date?**
A: Morning.  Exp Date of current stock is 09/2023.  Hope that helps.

**Q: Can I use this to seal a roof vent on my camper? I need to make sure it is completely watertight. Thank you**
A: Yes , you can , and it will seal against water ingress, It's also used for sealing deck fittings on a yacht or seagoing motor cruiser.

**Q: Would this work for waterproofing cracks in outside concrete steps**
A: Probably would, but I would try concrete first of all to fill the gaps, it would look better.

### ⭐⭐⭐⭐ Ok
*by A***R on 3 August 2025*

This stuff is great for so many boat related jobs! but the biggest issue is it sets solid in the tube!!!! and if you don't use it all at once, it very quickly becomes useless and it's too expensive for that!!!! Perhaps a something to stop this would really help 🤷
