Just what I needed!
Excellent quality.

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.

Dries Darker than Wet
The media could not be loaded. At first, it’s shocking to see it wet bc it looks like a chalky pink. After drying it darkens to a milk chocolate. Depending on how light strikes it varies the color depth. It went on smoothly. I moistened my finger to smooth easily which dried nicely next day. This is in my sunroom which’ll house my plants in winter as well as hibernate a few fishes. Can’t wait to receive the last bottle to complete. It had no fumes or noticeable smell. I had a fan going n my windows open bc it’s bn hot n humid. The batch of caulk that I received was fresh n easy to use. Not hardened at all. Very consistent in texture.

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.

An odd Brown?
Not what I would describe as brown; more of a purple-brown. The purple broadcasts through with one coat of light milk-chocolate brown paint... disappointing.
