## Questions & Answers

**Q: Will this work to seal out water between french doors?**
A: You bet it will.
I use it on my RV trailer to seal out the water on my outside  compartment doors, works well just like the rubber on your refrigerator that  keeps in the cool, it's that same kind of rubber. Superior, and long lasting product.
It's been two years now and it still looks new!

**Q: Hi, does this work on a window in texas heat 100 degree weather sun?**
A: This is basically the same kind of rubber on your refrigerator only smaller, but the same density and strength.  No 100 degree weather should affect it.
I used it to seal up my hatches on a 26 Foot RV Trailer 2 years ago and it still loos like new today, and seals out all weather air, cold and hot.
Works for my needs to keep hot and cold air OUT.

**Q: Anyone ever used this on a cooler to make ice last longer? Saw it on a video, wonder how well it would work long term.**
A: This would be a $5 low risk experiment you can try yourself.

**Q: Length of 17 ft means seal across top of door will be in two pieces, right? Strip is 2 ribs, each is 8.5 ft. Door is 7 ft tall, leaving 1.5 ft per rib**
A: Most doors are 6'-8" x 36" and would take 16.3 feet to go around the door.
