I had to go back and confirm which Sikaflex was used...both at diferent times it appears. I had to request the AS dealer, who had never heard of Sikaflex following: White 715 for the 2 FV replacements and White 221 for the Peel n' Seal of the roof seams. They did use the butyl tape as the gasket.
two of Lewster's posts on the Sealants thread.
I use 221 in white for roof seams, 221 grey for windows, doors and general sealing on aluminum and 715, which is a silane terminated polymer (doesn't harden and crack) for major roofing seams and around protrusions like fans, vents, skylights, etc. as it is self leveling."
DON'T apply SikaFlex 221 to anything that you may eventually want to remove, without a replacement going in it's place. It is extremely tenacious and there is no known solvent.. mechanical removal is the only process that works.......and it ain't easy!!!!!"
