## Questions & Answers

**Q: Can this be applied to rust?**
A: I think all these products will work better if you clean off any surface corrosion as best you can. I went round with a wire brush for a long while before applying it. This was last year and I will have to get underneath to inspect it all and find out how effective it was in protecting the underneath over the winter.

**Q: Does it stay sticky after spraying or does it dry to a smooth finish?**
A: It’s good stuff - it dries hard enough not to be sticky - and it’s not a smooth finish -however it’s not too textured either

**Q: what colour is it ?**
A: It's black

**Q: Can this be painted over?**
A: Hi, No this stays tacky. It’s and under seal and not like stone chip paint. I like it though and use it on chassis rails etc.
