## Questions & Answers

**Q: can it be painted on**
A: Yes, I used a paint brush to paint my shed roof

**Q: Does it fill small gaps in your shed roof**
A: Hi, Thompson's 10 Year Roof Seal needs to be applied to the whole roof. It cannot be used to fill in small gaps.

**Q: Would this product work on a aluminium motorhome roof**
A: Hi, we would not recommend the use of our Thompson's 10 year Roof Seal on an Aluminum roof as it will not adhere effectively.

**Q: Can it be use for a caravan awning**
A: I would not use it for an awning simple because I do not think an awning is made of rigid  material. It would simply be to heavy after it was applied even if you could get it to stick to an awning as well as the awning would not fold up afterwards. Definatly no
