Hi Jonathon,
You probably have your answer but I just re-did my seams and used the paintable caulking. Taped the edges about the same distance apart as the old tape and filled with the caulking and smoothed out to tape edge. Textured it with a cleaning sponge- looks really good and blends in more than old tape. I did have to run an exacto knife along the tape edge before pulling off as the caulking is so rubbery. Waiting for the temp to actually be summer like so I can
paint it. Can send pics if interested
