Hi @cmmullins - Thanks for reaching out!
We do carry polyurethane tent treatments, but are currently out of stock. We have reached out to our product team to see about a timeline for future availability. We will respond here when we have an update for you.
In the meantime, if you have additional questions about the resealing process, we suggest looking through this replacement rain fly thread that has lots of great feedback from other customers about what they used and their techniques on resealing tents.
Hi @cmmullins - It looks like the Nikwax Tent and Gear SolarProof Waterproofing Spray is currently in-stock and is a good option for your tent floor and rainfly.
Let us know if you have any additional questions and we'll be happy to help!
