Along the roof seem which makes contact with the gutter, their is a bead of caulk or something else. It is starting to show its age in spots. Which type of caulk do you use to touch up any problem areas. Can I use eternabond tape along the entire edge. If there is specific caulk to use, that would be beneficial too.
thanks

You want a non sag formula, not self leveling for that application.
There is standard Dicor lap sealant, which is for EPDM, and Dicor Ultra, which is for TPO. If you use standard Dicor on TPO there is a possibility of it reacting with and bubbling the TPO, depending on the TPO. Some will bubble, some won't.
You do not list your RV manufacturer. A lot of manufacturers have been using Alpha Systems Superflex roofing, not an EPDM or TPO but a modified vinyl. A lot of Forest River brands have the Alpha ply roofs. In that case you want to use Alpha Systems Superflex Total Protection sealant which is available in both self leveling and non sag formulas.
