My experience also. Butyl. Another observation -- some have posted that they plan to wrap a chainplate in wax paper and cast it in epoxy. This is not a good scheme as now your sealant is hard epoxy. Water will wick down the joint. Leave a 1/8" to 1/4" gap around anything that penetrates the deck to allow butyl to seal the joint.
