Does Butyl Rubber tape have any adverse reaction with cast Acrylic
We are 1/2 way through rebedding our portlights
, and I hate tube goo!....
are three pieces, designed to work with a flange built into the boat. On the outside, is an aluminum
trim ring with holes. Next is the acrylic
, also drilled with holes. The acrylic sits inside a flange built into the cabin
sides, and the outside trim ring covers up the edge of this flange and the acrylic.
Inside is another trim ring. Barrel, or "Sex" bolts, are used to compress the stack together. I was using Down 795 to put these all together, but I have some of Mainesail's Butyl Rubber tape, and thought it would be a better solution, with tape used between the acrylic and the cabin
side flange, and then also on each bolt head
, to keep out water
. Also some between the outer trim ring and the acrylic.
Good idea? Did I say I hate tube caulk?
