## Questions & Answers

**Q: Would this work on a plastic rear motorcycle fender?**
A: Yes, it should do, though I haven't personally tried it.

**Q: Would this work for filling in cracks in a pavement / curb?**
A: What's the pavement / curb made of? How deep are the cracks and how many of them are there? How long are they? Is the pavement adjacent to the curb? Is the curb next to a main road? What's the footfall on the pavement like? If it's a main road do buses and trucks use it? I don't think so! I may be wrong. As Isopon!

**Q: Would this fix a hole in the bottom of a fibreglass boat**
A: It’s an amazing product and easy to use. I think it would fix a hole but I am insufficiently experienced in diy to know about a hole in a boat!

**Q: I have a glass fibre garden statue that has a deep hole will this work as a filler or is it just to put on metal**
A: yes this would work
