The channel was quickly cleaned and cleaned and the band was quickly attached to the desired locations. Since the channel is kept in silver, we have not painted the tape. The result is impressive and has already survived the first summer storm without any problems. Thus we have the same other smaller leaks covered with the sealing 38 - These included sporadic holes in carport roof and pipe crossings. Again, there is no complaint, keeping the tape what it promises - it's all up to now close.
Whether the 3M now the next few years, and especially during the winter is I can not write at this point but it is just assumed. The sealing tape is with its 1.5 m not very cheap but has been more sustained than the cheaper from a hardware store.
