## Questions & Answers

**Q: Would you use this on the whole area**
A: It's only required on the rotted area.  Cover the entire rotted area, allow to dry then rub down.

**Q: How long between applying coats?**
A: About four hours. Longer if colder. If you are using wood filler allow about 12 hours after wood hardener is applied.

**Q: Under the cap, there’s a little metal lid that seems to be welded on!! Any advice on how to take it off safely? I’ve tried a stanley knife but nope.**
A: I used a screwdriver to prize it off. Not easy but don't worry about destroying the metal lid.

**Q: Does this dry clear, or milky white?**
A: It dries clear unless it gets wet before drying - then it is milky white - I found the same with the Ronseal product
