ive read a lot of opinions. i know i could probably go with a 100% silicone sealant for the storm collar , but im not sure about under the flashing, and also the shingles where i will need to pop the tar strip apart and reseal. they do make 100% silicone black, which has a high heat resistance, but i didnt know if there was one type of sealant that i could use for it all that would be clear. i know for sure i want to use a clear sealant, and if i could use something more permanent under the flashing in stead of the 3-4 year range of 100% silicone, that'd be want i want. is there something between 100% silicone and tar i guess is what im asking.
