## Questions & Answers

**Q: What is the shelf life of this epoxy?**
A: Detailed information can be discovered by contacting West Systems technical staff at 866-937-8797 or via e:mail at tech-support@westsystem.com

**Q: How much does this 8 oz cover?  Approximately howmany rivets would this cover?**
A: This is a highly subjective question with a lot of variables. If used somewhat conservatively it will easil cover 100 + Rivets.

**Q: Is it somewhat rubbery or pretty firm after it cures?  Could anyone please describe it?**
A: it is not rubbery, it hardens to a very firm coat; how hard is dependent on your mix. it is flexible and holds together; however, less hardener the more flex with coverage. i have used it to gack bows, and it works well.

**Q: is this an 8 oz bottle of the resin and an 8 oz bottle of the hardener?**
A: It's 4 + 4 mate. 8 oz in total
