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.
