Just wanted to pass along something I found that may be useful to others.

As you can see from the pics attached, our screw cover/trim molding on the exterior was in pretty poor shape. After much research, I found an Amazon supplier that would send samples of various sizes and colors for just the cost of shipping. So I ordered a set and they turned out to be really nice.

While all three profiles (1/2", 5/8" and 3/4") would fit into the slot, the 5/8" gave us the look we were going after and provided a solid seal. The 1/2" was a little loose and the 3/4" bulged a little more than we preferred.

Anyway, here's some before and after pics, along with a profile of what we took out vs. the new. I'm also attaching a pic of the sample I ordered in case someone else is interested. I have no connection with this seller and get nothing in return. And since I just installed it, I am not sure about longevity. However for now at least I have a good seal and it look so much better!!

Hope this helps someone!
