Quality caulk
Brown caulk worked just fine no issues

Fills BIG 1/4" gaps in wood siding, no problem. Awesome stuff, easy application
Using old-school white latex caulk on outdoor trim leaves a lot to be desired, namely it shrinks and splits where you need it to seal. Enter DAP Dynaflex. This fills BIG cracks, a bit over 1/4" just made it yawn and say, "can you please give me a challenge?" Flows and applies easily with a caulk gun, and if the label can be believed, stays pliant and won't fail. Time will tell, but so far so good.

Good color match.
This color, like other DAP colors, was a good match to our wood floor, which was the reason I chose this color of calk. Cure time was not excessive and adhesion was good. I've had good luck with DAP colors in the past and this was no different.

Good
Maybe I am color blind, but it is not a brown brown, but red brown, although the package displays really nice brown color! It is a good sealant that was easy to work with! It has good performance and is durable so far! I don’t like how the color appears different! Since the brown one is hard to find in the store, I was happy to get it from Amazon, although it is a bit pricey!
