## Questions & Answers

**Q: Is this the right product to use when adhering a keel protector to the bottom of a thermoformed plastic skin or hdpe kayak?**
A: No it is not, not much sticks to hdpe, I would look at a plastic welder

**Q: Will this work with adhering marine grade carpet on treated lumber for bunk boards on boat trailer for use in saltwater?**
A: No. This glue expands just like expandable foam filler or insulation.

**Q: will this work to glue wood strips to styrofoam in a boat seat?**
A: Depends on the foam. If the glue is compatible with your particular foam, and does not melt it, it would work. Watch the shelf life on this glue. It is only about a year.

**Q: Will this glue work with rubber?**
A: This type of glue is only suited for nonflexible joints.
