Re: Bedding Deck Hardware With Butyl Tape
You could seal the deck with Cetol or any of a number of varnishes out there.
Yes, I would seal deck hardware to a wood deck with it.
I do NOT think I would use it for below-the-waterline applications. There are some things that the 3M products are still good for.
