Performs exactly how it's marketed to.

I'm replacing the south facing windows in my house and needed some caulk to seal them with. I had replaced the north facing windows years ago and used Alex Plus caulk, which while easy to apply and cleanup didn't hold up in the long run. It cracked and shrunk. Dynaflex Ultra goes on just as easy and is also easy to cleanup, but unlike silicone can be painted and also remains flexible after curing unlike the Alex Plus. I live in Colorado and this stuff has been applied to south facing windows so it's going to get tested to the extreme. We have temperature swings that can approach 100F on south facing surfaces all winter long, and extreme low humidity (1% was registered on my weather station twice) in the summer. If it holds up here it will work anywhere but only time will tell. That being said I'm impressed enough that I'm sitting here writing a review on caulk so that should tell you something! I'll try and return with an update after 6-12 months to see how it holds up this winter.

DAP Dynaflex ULTRA great for weatherization projects

[This review was collected as part of a promotion.] Currently we're experiencing well below zero temperatures and I'm very happy with the way Dap's Dynaflex Ultra has worked to seal those tiny cracks preventing moisture and air infiltration. It's been keeping our home warmer this winter and protecting the exterior wood around the windows and doors from the melting and freezing cycle where little drips get into the smallest places and damage the wood. It works well in lower temperatures - it was around 40 degrees when I applied it earlier this month and it's holding up well to rain, snow, sleet and wind. While I did try this as a free sample through Viewpoints, I have since purchased several more tubes at our local hardware outlet and will continue to buy this product because it gets the job done - and done well.
