Hi Dwight, 

Where do you buy butyl tape?

I used 1/8 thick grey butyl tape when I did the teak handrails on my C&C 27 some years ago.  I cut strips of tape large enough to cover each base entirely and trimmed around the edges after the handrails were tightened down.  It is a 2 person job for sure and I found out that I needed to make pilot holes in the tape for the screws or else the tape sort of wound itself around the screws as they went through it.  I think if you get it right the butyl tape is the best product for bedding teak handrails on our boats.  There is too much of a tendency to tighten things down too much the first time when using Sika or boatlife or any soft caulk and that affects the thickness of the gasket formed.  Also the tape is not as messy as the caulk to work with and it lends itself to future tightening. I will be doing the handrails on my 35 this spring and I will use butyl tape.  I thought about getting stainless handrails made but that could be quite expensive.  In the end I decided I liked the look of teak better than stainless on my old boat.

I've tried several different things . For example I used 3M- 4200 and had reasonable luck for several years and I think the 4200 helped to keep the rails tight. 

But this last time I used butyl tape because It seems to still be the best for stopping leaks and also holds well but not as well as 4200. 

It's really a guessing game but in your case because your rails are bolted together right through the roof I don't think you need to worry about an adhesive . you're most concerned with stopping all leaks and so I considering butyl tape.
