I have successfully for years used white Eternal bond tape in various widths to cover seams, small tears and road debris damage to my TT with only limited recaulking needed where I could not afix the tape in other areas. The tape is very durable, thick and last a long long time AND IS quick and easy to use and absolutely mess free. I applied it over the old caulk in many places and it looked nice and white like rest of the TT. In addition I used Dicor liquid rubber roof to cover the whole roof and tape. Glad I bought a white TT. Never any leaks from harsh wx elements always out in the open with no covers or carports. This method should also work on TC.
For me the tape was almost like caulk and very malleable with no time constraints once exposed to air unlike caulk. Your mileage may vary.
