Gap Between Trex and Concrete


I need to fill a gap and want to know the best way. The gap is between a Trex deck fascia board (that covers a deck rim joist) and the stamped concrete walkway. The gap is mostly 1/4" or less, but increases to about 3/8" in some spots. Do I use special caulk, Okum or what? I want it to preferably match the grey deck boards. Thank you.

I'm not sure what Trex is but I would use a foam backer since the gap is so wide. Then I would put in the self leveling caulk from HD in the concrete department. Lowes probably has a similar product or even Ace Hardware.
