Do a goggle on SikaFlex 291, the sika site lists this as "temporarily
resistant to fuels, mineral oils", ect,
Sounds like this is more of gp marine adheasive/sealant that would be
useful in some medium duty bonding and sealing and the 292 is more of a
heavy duty bonding type product for things like hull to deck joints.
