I will mention that I did the lens bedding to the aluminum hatch
frame portion of the job from the comfort of my shop this winter. I used "GE ssg4000 ultraglaze" in black which I assume is very similar to "3m 4000uv". Both are silicone, both are uv resistant. I went with the ultraglaze because apparently it is what they use to bed
windows on skyscrapers.....figured that was convincing enough.
Another point I might mention is that I discarded the original 1/8" acrylic
lenses and made new ones out of 1/2". Many advantages to going much thicker, one being reducing flex and therefore reducing the possibility of a seal being compromised by motion.
Good luck with your project!
