I used a thickened CA for the wire handrails and wire piping details. I took my time and beveled the lenses so that they fit snuggly into the fixtures so that the lens is pretty much flush with the rim. I used a couple small dabs of CA off of a toothpick and placed them into their respective fixtures with no issues of fogging. Many two part epoxy resins are not a true clear when mixed and usually harden with a slight amber tint.
