I've used butyl tape in rare circumstances when the hardware being bedded is chemically incompatible with Sikaflex or 3M.

Dave - you're a font of wrinkleboat knowledge. Thanks so much! Is there a way to know the chemical compatibility? Are there particular plastics that are definitely incompatible? Most of the hardware I'll be over-drilling / epoxying / re-drilling / re-bedding is some sort of plastic. Most of it is original to my 1988 M-15, but a I have a couple of more recent Harken cam cleats. Charlie
