I like the idea of using tape. I had some suspicious spots on my rear edge and taped it there. I did not like the look of taping over the caulk but did so.
Question-- how hard to remove the lumpiness of the caulk for a smooth/neat/prettier finished look? Next summer I will be looking at the rest of the seams on my 2017 so would like to be prepared. (30+ years of Scouting) to do my best.
