I am redoing a 2005 sprinter van roof after discovering leaks in the seams and around fans, skylight and vents. After reinstalling everything, applying sealants (Diacor around the fan and skylight and sikaflex 221 on the seams), I am considering covering the sealants with eternabond tape as an added protection. Any issues with using eternabond tape for long-term protection? Is it overkill? Thanks!
