Review: this works great.
Review: So this was a shot in the dark purchase. I had a small portion of my RV slide floor getting weak and brittle from a previous leak. I was not ready to remove the floor yet so I used this product as a hope of extending the repair. I purchased a meat injection plunger and injected this product where all of the softness was. To my absolute amazement, this stuff made it hard as a rock. The floor is so solid that I don't even have the repair scheduled to be done. This stuff is very impressive and was ready to use unlike other on the market.

## Questions & Answers

**Q: Will this strengthen the partially rotted tops of 4 x 4 red wood deck posts, fill the rot cavity, and firmly hold screws?**
A: I have used this product and Minwax wood hardener. Minwax is the better product. It penetrates deeper and strengthen the wood. I wood follow up with an exterior grade wood filler to fill any rotted out voids then carry on with your fasteners.

**Q: how is it applied?**
A: I am a fan. However there is no way it can be sprayed on. it's very thick and i can't comprehend it being in a spray bottle. Think honey or syrup. As a handyman profesional I love this. I just did 3 days doing roof trim repair that had rot and carpenter ant damage. The fibers are loose like straw. this firmed them up enough for me to put in wood epoxy.

**Q: Chemically, what is this stuff?**
A: http://www.jb-weld.co.uk/images/technical-data-sheets/J-B-Weld-MSDS-Wood-Restore-Epoxy1.pdf

**Q: Can this be used outdoors?**
A: yes it can. I used it on exterior window trim.

This worked like magic. I used it on the somewhat rotten wood then filled it with putty and painted the wood. It saved the fence and saved a lot of money.
