Using silicone on a rubber roof?

Thanks for the help. Amazing how one caulk wont sub for another. I figured almost anything would be OK. I will check out the Eternabond and BU caulk tube option.

Hi Old Biscuit! Yes, have not had to bother the group for many years. My Northstar TC has been fine for all this time. Now it is starting to age and had some problems / questions. I told you I would be gone once my rig was in ship shape and I was good to my word. Thanks for remembering me!
