Review: Good sealing, very helpful in difficult conditions but a little be temperature sensitive - Good sealing, very helpful in difficult conditions but a little be temperature sensitive so when I tried to apply it during a wind storm, cloudy, sunless day at 47º F, it was stiff and stuck to my fingers more than it stuck to the window frame. I still recommend it really did stop the significant cold air leaks (and small leaks as well) which is exactly what we wanted, When the temperature is a little bit warmer its easy to apply but when the metal window frame got down to 47º F in high winds, it got still and did not stick to the metal frame so much, I could still push it into place into the grooves that were laking a huge amount of air. NOTE: Even a tiny hole can leak a massive amount of air, so its best to use more and push it into every possible crevice to trite catch all the possible leaks. When the window temperature is cld and the caulk doesn't want to stick to the cold metal frame, it will tend to stick to your fingers so push in to the slot/crevice then slide or twist your finger to release the caulk (don't worry it washes easily off you're fingers so push it as hard as necessary to get it to stick to the frame). You will notice that once you install it that when it's cold it will harden, don't worry, it still seals the window and keeps the drafts out. When the temperature rises then it will soften again and if you need to you can then work it into the gap/crevice some more. Although its listed as 45 feet which sounds like a lot, keep in mind that it comes in 5 rows, you can tear off 1, 2, 3, 4 or 5 strands and install them, so very often you will use more than 1 strand (I often used 3 or 4 strands) so I was only able to seal one and a half standard sided windows (which is all I added to do anyway), at its low price its certainly worth buying more if you need it, use plenty so it seals your windows properly. I would give it a 5 start rating other than a slight challenge with installing it at cold temperatures (which it still got installed, it just took more effort, that was worth it).

## Questions & Answers

**Q: Is it easy to remove when the weather warms up?**
A: This is the reason I love this stuff!  You can apply it in the winter and pull it off in the spring.  It is so cheap, but I have also saved thicker strips for re-use by storing in a baggy and then using them in the out of the way places like a cellar window where I am not so concerned about the look of it being patched together.  You can't beat this stuff for the price!

**Q: Can this be applied outside in cold temps (20F or below)?**
A: Yes, you can apply it if the temperatures are 20F or below.   Please note that you need to divide the sections so that you have only the width that you need.   Then you need to push it INTO THE SPACE OR INTO THE CRACK for it to stay in place.

**Q: 5.5 x 5.8 x 1.2 inches? These dimentions don't even come close to the photo or a 45 foot roll. anybody have a clue?**
A: Roll has 8 single strings of caulk which are rolled over and over again but are attached like licorice strings. It’s a lot and I have a 90 ft roll. The strings are a little thin an 1/8 of an inch in diameter x 90 ft long but they work.

**Q: I have sliding windows, and patio door.  Will the grey work good to seal the drafts on them?**
A: Absolutely!  I wasn't sure how good it was going to be so I ended up ordering more. I bought the wood - colored one as well to put on places where wood meets the sill, as I could feel air seeping in.  I can't say how great this stuff is.  I've got it on all my windows.  It's very easy if you need to adjust it and taking it off is a breeze. You can peel it off in whayever is needed....thin, medium or thick pieces.  It's inexpensive as well!  I needed to write this review for you because I believe when you're going to buy a product...it's nice to hear from someone who has used it if it's good or not. Again, great great product and price!!
