I needed to seal some gaps between the frame of a patio door and the surrounding wall. I am not a professional, but I found this to be perfect for my purposes. It sealed the gaps and cured really well. I used it about a couple of weeks ago. Time will tell how long it will last and work over time and after a long exposure to sun, cold, and rain but so far so good.

DAP is a good brand and this worked very well, but we needed a dark color and man, it was messy! But once everything got done and cleaned up, it's did its job just fine.

Covered roofing screws on a metal roof to stop leaks. Goes on easy and is "thinner" than other caulking. I'll see what the summer sun does to it.
