## Questions & Answers

**Q: Can i use this for my transom outer skin? Just finished installing new transom wood and need to paint the outer skin.**
A: I would use their two part epoxy “total fair” for that.  I used it to fill very deep grain in my hull, and it’s great. The polyester fairing compound is difficult to know how much hardener to use, and some of it didn’t cure properly.

**Q: Can you ise this to repair boat flooring?**
A: You may only use it to fair (fill in small dips in the final laminate of fiberglass mat and resin, making the surface flat) before applying gelcoat or paint. This polyester resin is not structural, meaning it should not be used to repair, say, a rotted floor.

**Q: Can this be used to repair ABS?**
A: This fairing compound is used to fill in slight imperfections in a fiberglass surface prior to painting, gelcoating, etc. There is minimal structural strength with this product. It is not as strong as ABS and would not stand up to the environment that ABS can stand up to. This is especially true if the compound repair is not covered with paint, gelcoat, etc.
