Review: Works as intended & very nicely. - Well, I wasted my money! Do not misunderstand so soon though; the seal works great for the first half of the door, for the second half it showed me the door is crooked! The adhesive sticks nicely, if you make a mistake, it allows you to go back & fix it as long as the paper is still attached to prevent the material from stretching or tearing. Once applied, you peel the tape off very easily. Looks good, if only I bought a thicker version of the same product, it would have been perfect for my use-case scenario. At-least now I know the door I used this with is not flush with the frame. So how do I fix this problem? Well, I am not going to be taking the frame off, possibly damage it, put it back on, and repaint it; so time to buy more Frost King Self-Stick Rubber Foam Weatherseal adhesive strips! Particularly the variety that stands out further so that it could make contact with the door!
Review: The best $2.93 item - Highly recommended - This is the best $2.93 I have invested recently. The drafty door was sealed immediately. Easy to install, and very effective. Highly recommended.

## Questions & Answers

**Q: Can you double up on it if it's not thick enough?**
A: Yes you should be able to with it being sticky it will stick to itself and double the thickness

**Q: Does it keep dust out?**
A: i used it on my comp , & i haven't had any problems with dust. just be sure to seal it tight when using it. Darlene.

**Q: Could this be used to fill gaps between door sides and frame where bugs are coming in?**
A: I believe so; we used this to fill a gap around our door. The intent was to keep the cold air from coming in during the winter months, but it works to seal the gap, preventing anything from coming in/out (air, bugs, etc.).

**Q: is this double stick?**
A: if you mean double sided adhesive, the answer is no
