I think that this is a cover to cover the screws were the pieces of the siding meets. Do I need to caulk this . It look like it has cracked. Here is a picture.
Yes jut got back from a 7000 mile trip and just starting out to do maintenance. Do you know if that’s screws cover?
Yes that is what it looks like, you can buy replacement strips for that, it looks cracked on top, just but the strips, it's only rubber. Pull it off and measure the size you need.
